Answered by Bot
f^5, because when you have the same base and you're multiplying exponents, you add the exponents. In this case, f has an exponent of 2 and an exponent of 3, so 2+3=5.

100^12
100^8
Answered by Bot
To simplify 100^12, you multiply 100 by itself 12 times, which is equal to 100,000,000,000,000,000,000,000.

For 100^8, you multiply 100 by itself 8 times, which is equal to 100,000,000.

100^12
_____
100^8
Answered by Bot
To divide these two powers with the same base (100), you can subtract the exponent of the denominator from the exponent of the numerator:

100^12 / 100^8 = 100^(12-8) = 100^4

Therefore, the simplified form of 100^12 / 100^8 is 100^4.

Answered by 6foot under
x^16 divided by x^3

Answered by Bot
When you divide two like bases with exponents, you can subtract the exponent in the denominator from the exponent in the numerator.

In this case, x is the base and the exponent in the numerator is 16 and the exponent in the denominator is 3. Therefore:

x^16 / x^3 = x^(16-3) = x^13

So, the simplified form of x^16 / x^3 is x^13.

which following expression
4^3 x 4^5 < 4^12
5^2 x 5^3 > 5^5
3^2 x 3^4 = 3^2
5^2 x 5^4 = 5^8
Answered by Bot
The correct inequality is `4^3 x 4^5 < 4^12`. This can be simplified to `4^8 < 4^12`, which is true since 4^8 is less than 4^12.

The correct inequality is `5^2 x 5^3 < 5^5`. This can be simplified to `5^5 < 5^5`, which is false since 5^5 is equal to 5^5, not less than it.

The correct equation is `3^2 x 3^4 = 3^6`. This is true because when you multiply two like bases, you add the exponents. In this case, 2+4=6, so `3^2 x 3^4 = 3^6`.

The correct equation is `5^2 x 5^4 = 5^6`. This is true because when you multiply two like bases, you add the exponents. In this case, 2+4=6, so `5^2 x 5^4 = 5^6`.

which following expressions is true?
4^3 x 4^5 < 4^12
5^2 x 5^3 > 5^5
3^2 x 3^4 = 3^2
5^2 x 5^4 = 5^8
Answered by Bot
The true expression is `4^3 x 4^5 < 4^12`.

To simplify this expression:

- `4^3` is equal to 64 since 4 multiplied by itself three times equals 64.
- `4^5` is equal to 1,024 since 4 multiplied by itself five times equals 1,024.
- `4^12` is equal to 167,772,16 since 4 multiplied by itself 12 times equals 167,772,16.

So we can rewrite the inequality as:

64 x 1,024 < 167,772,16

When we multiply 64 and 1,024 we get 65,536, which is indeed less than the value of `4^12`, so the inequality is true.

which of the following expression is true?
2^4 x 2^3 = 2^12
3^3 x 3^6 > 3^8
4^2 x 4^2 > 4^4
5^5 x 5^2 = 5^10
Answered by Bot
The true expression is `2^4 x 2^3 = 2^7`.

When you multiply two like bases, you add the exponents. In this case, `2^4` is equal to 16, and `2^3` is equal to 8, so `2^4 x 2^3` is equal to `16 x 8`, which is equal to 128, or `2^7`.

Therefore, the expression `2^4 x 2^3 = 2^7` is true.

4^5 divided by 4^5
Answered by Bot
The value of `4^5 divided by 4^5` is 1.

When you divide two like bases with exponents, you can subtract the exponent in the denominator from the exponent in the numerator.

In this case, `4` is the base and the exponent in the numerator is 5, and the exponent in the denominator is also 5. So:

`4^5 / 4^5` can be simplified to `4^(5-5)`, which is `4^0`.

Any number (except for 0) raised to the power of 0 is equal to 1. Therefore, the value of `4^5 / 4^5` is 1.

2^2 divided by 2^5
Answered by Bot
To divide two like bases with exponents, you can use the rule where you subtract the exponent in the denominator from the exponent in the numerator.

In this case, `2` is the base, and the exponent in the numerator is `2`, and the exponent in the denominator is `5`. So `2^2 / 2^5` can be simplified as follows:

`2^2 / 2^5 = 2^(2-5) = 2^(-3)`

The negative exponent means that the base is in the denominator. So the value of `2^2 / 2^5` is `1/2^3` or `1/8`.

(2.3 x 10^1)(7 x 10^6)
Answered by Bot
To multiply two numbers in scientific notation, you can multiply their coefficients and add their exponents.

Using this rule, we can multiply `(2.3 x 10^1)(7 x 10^6)` as follows:

`(2.3 x 10^1)(7 x 10^6) = (2.3 x 7) x 10^(1+6)`

`= 16.1 x 10^7`

So `(2.3 x 10^1)(7 x 10^6)` is equal to `16.1 x 10^7` in scientific notation.

(1.1 x 10^-5)(3 x 10^-2)
Answered by Bot
To multiply two numbers in scientific notation, multiply their coefficients and add their exponents.

Using this rule, we can multiply `(1.1 x 10^-5)(3 x 10^-2)` as follows:

`(1.1 x 10^-5)(3 x 10^-2) = (1.1 x 3) x 10(-5-2)`

`= 3.3 x 10^-7`

So `(1.1 x 10^-5)(3 x 10^-2)` is equal to `3.3 x 10^-7` in scientific notation.

7t^4 x 7t^4
Answered by Bot
To multiply two monomials with the same base, you keep the base and add the exponents.

In this case, the monomials are `7t^4` and `7t^4`. Since both monomials have the same base (`7t^4`), you can multiply them as follows:

`7t^4 x 7t^4 = (7 x 7) x (t^4 x t^4)`

`= 49 x t^(4+4)`

`= 49t^8`

So `7t^4 x 7t^4` simplifies to `49t^8`.

-x(7x-8)
Answered by Bot
To multiply `-x(7x-8)`, you need to distribute `-x` to each term inside the parentheses.

So:

`-x(7x-8) = -x * 7x + (-x) * (-8)`

`= -7x^2 + 8x`

Therefore, `-x(7x-8)` simplifies to `-7x^2 + 8x`.

3k^2(-2k^2-4k+7
Answered by Bot
To multiply `3k^2(-2k^2-4k+7)`, you will need to distribute the `3k^2` to each term inside the parentheses.

So:

`3k^2(-2k^2-4k+7) = 3k^2*(-2k^2) + 3k^2*(-4k) + 3k^2*(7)`

`= -6k^4 - 12k^3 + 21k^2`

Therefore, `3k^2(-2k^2-4k+7)` simplifies to `-6k^4 - 12k^3 + 21k^2`.

(3k + 2)(k - 3)
Answered by Bot
To multiply `(3k + 2)(k - 3)`, you can use the FOIL method which stands for:

- First: multiply the first terms in each set of parentheses
- Outer: multiply the two terms on the outside (the first term in the first set of parentheses and the second term in the second set of parentheses)
- Inner: multiply the two terms on the inside (the second term in the first set of parentheses and the first term in the second set of parentheses)
- Last: multiply the last terms in each set of parentheses

So:

`(3k + 2)(k - 3) = 3k * k + 3k * (-3) + 2 * k + 2 * (-3)`

`= 3k^2 - 9k + 2k - 6`

`= 3k^2 - 7k - 6`

Therefore, `(3k + 2)(k - 3)` simplifies to `3k^2 - 7k - 6`.

(-y+4)(2y-1)
Answered by Bot
To multiply `(-y + 4)(2y - 1)`, you can again use the FOIL method:

- First: Multiply the first term of each expression: `-y * 2y = -2y^2`
- Outer: Multiply the outer two terms: `-y * -1 = y`
- Inner: Multiply the inner two terms: `4 * 2y = 8y`
- Last: Multiply the last term of each expression: `4 * -1 = -4`

Putting it all together:

`(-y + 4)(2y - 1) = -2y^2 + y + 8y - 4 = -2y^2 + 9y - 4`

Therefore, `(-y + 4)(2y - 1)` simplifies to `-2y^2 + 9y - 4`.
