Answer 4

Apply the Zero Power Rule to create an equivalent expression to 9⋅(−33)0+32(8−270) .(2 points)
9⋅(−33)0+32(8−270) = ⋅ +32( – )

Answer 5

By applying the Zero Power Rule, any base raised to the power of 0 equals 1. Therefore, we can simplify the expression as follows:

9⋅(-3)^0 + 32(8-27^0)
= 9⋅1 + 32(8-1) (since (-3)^0 is equal to 1)
= 9 + 32(7)
= 9 + 224
= 233

So, the equivalent expression is 233.

Answer 6

9⋅(−33)0+32(8−270) = ⋅ +32( – )

Answer 7

9⋅(-3)^0 + 32(8-2^0)

Since any base raised to the power of 0 is equal to 1, we have:

9⋅1 + 32(8-1)

Simplifying the expression further:

9 + 32(7)

Now we can calculate the product of 32 and 7:

9 + 224

Finally, adding 9 and 224 together:

= 233

So, the equivalent expression is 233.

Answer 8

9⋅(−33)^0+3/2(8−27^0) = ⋅ +3/2( – )

Answer 9

By applying the Zero Power Rule, any base raised to the power of 0 equals 1. Therefore, we can simplify the expression as follows:

9⋅(-3)^0 + 3/2(8-1)

Since (-3)^0 is equal to 1, we have:

9⋅1 + 3/2(8-1)

Simplifying further:

9 + 3/2(7)

Now we can calculate the product of 3/2 and 7:

9 + 21/2

To add the fractions, we need a common denominator:

9 + 21/2 = 18/2 + 21/2 = 39/2

So, the equivalent expression is 39/2.

Answer 10

Fill in the blanks
9⋅(−33)^0+3/2(8−27^0) = ⋅ +3/2( – )

Answer 11

9⋅(−33)^0+3/2(8−27^0) = 9⋅1 + 3/2(8-1)

Answer 12

Solve the expression
15 times 8^0/5 + (7^0 - 6) =

Answer 13

Recall that any number raised to the power of 0 is equal to 1. Let's solve the expression:

15 times 8^0/5 + (7^0 - 6)

Starting with the exponentiation:

15 times 1/5 + (1 - 6)

Now, multiply and simplify:

= 15/5 + (-5)

= 3 + (-5)

= -2

So, the expression equals -2.

Answer 14

Use the Power Rule of Exponents to simplify (103^)^6 .(1 point)

Answer 15

The given expression is (103^)^6.

To simplify this using the Power Rule of Exponents, we need to multiply the exponents.

The Power Rule states that when you have a power raised to another power, you multiply the exponents.

In this case, the exponent outside the parenthesis is 6 and the exponent inside the parenthesis is 3.

So, multiplying the exponents, we get:

(103^)^6 = 103^(6 * 3) = 103^18.

Therefore, the simplified expression is 103^18.

Answer 17

The expanded equivalent expression of 715, using the Power Rule of Exponents, would be:

(7⋅7⋅7)⋅(7⋅7⋅7)⋅(7⋅7⋅7)⋅(7⋅7⋅7)⋅(7⋅7⋅7)

So, the correct response is: (7⋅7⋅7)⋅(7⋅7⋅7)⋅(7⋅7⋅7)⋅(7⋅7⋅7)⋅(7⋅7⋅7).

Answer 18

Use the Power Rule of Exponents to create a simplified equivalent expression for (19^4)^9 .(1 point)

Answer 19

To simplify the expression (19^4)^9 using the Power Rule of Exponents, we need to multiply the exponents.

The Power Rule states that when you have a power raised to another power, you multiply the exponents.

In this case, the exponent inside the parentheses is 4, and the exponent outside the parentheses is 9.

So, multiplying the exponents, we get:

(19^4)^9 = 19^(4 * 9) = 19^36.

Therefore, the simplified equivalent expression is 19^36.

Answer 20

Apply the Property of Negative Integer Exponents to solve 7^−3 . The answer should not contain any exponent expression or decimals.(1 point)
7^−3=

Answer 21

Applying the Property of Negative Integer Exponents, we know that any number raised to a negative exponent is equal to the reciprocal of that number raised to the positive exponent.

So, for 7^(-3), we can rewrite it as:

1 / 7^3

Simplifying further:

1 / (7 * 7 * 7)

1 / (343)

Therefore, 7^(-3) simplifies to 1/343.

Answer 22

Answer 23

I apologize for the mistake in my previous response. Let me correct it:

Applying the Property of Negative Integer Exponents, we know that any number raised to a negative exponent is equal to the reciprocal of that number raised to the positive exponent.

So, for 7^(-3), we can rewrite it as:

1 / 7^3

Simplifying further:

1 / (7 * 7 * 7)

1 / (343)

Therefore, 7^(-3) simplifies to 1/343.

Answer 24

Apply the Property of Negative Integer Exponents to generate an expression equivalent to 3^−17/8^−14 with positive exponents only.(1 point)
3^−17/8^−14=

Answer 25

To apply the Property of Negative Integer Exponents and generate an expression with positive exponents only, we need to flip the base and change the sign of the exponent.

For 3^(-17), we can rewrite it as 1 / 3^17.

Similarly, for 8^(-14), we can rewrite it as 1 / 8^14.

Substituting these expressions back into the original equation, we have:

3^(-17) / 8^(-14) = (1 / 3^17) / (1 / 8^14)

To divide by a fraction, we can multiply by its reciprocal:

= (1 / 3^17) * (8^14 / 1)

Applying the rule for multiplying exponents, we have:

= 8^14 / 3^17

So, the expression equivalent to 3^(-17) / 8^(-14) with positive exponents only is 8^14 / 3^17.

Answer 26

Apply the Properties of Integer Exponents to generate equivalent expressions to (7^−3)^7 ⋅ 7^20/6^−2 with only positive exponents, then solve the expression. Provide the answer as an improper fraction.(1 point)
(7^−3)^7 ⋅ 7^20/6^−2

Answer 27

To simplify the expression (7^(-3))^7 * 7^20 / 6^(-2) using the properties of integer exponents, we can first work within the parentheses, then combine the terms.

First, let's simplify the expression within the parentheses:
(7^(-3))^7 = 7^((-3)*7) = 7^(-21)

Next, let's simplify the expression outside the parentheses using the property of multiplying exponents with the same base:
7^20 * 7^(-21) = 7^(20 + (-21)) = 7^(-1)

Finally, let's simplify the expression involving 6 using the property of negative exponents:
6^(-2) = 1 / 6^2 = 1 / 36

Substituting the simplified expressions back into the original expression:
(7^(-3))^7 * 7^20 / 6^(-2) = 7^(-1) * 7^20 / 1 / 36
= 7^(-1) * 7^20 * 36
= 7^(-1 + 20) * 36
= 7^19 * 36

Therefore, the simplified expression is 7^19 * 36.

Answer 28

Apply the product rule of integer exponents to find the numerical equivalent of 12^−5⋅12^7 . Show your work and explain how you used the product rule of integer exponents.(2 points)

Answer 29

The product rule of integer exponents states that when multiplying two numbers with the same base, you can add their exponents.

In this case, we have 12^(-5) * 12^7. To find the numerical equivalent, we can use the product rule of integer exponents to combine the exponents:

12^(-5) * 12^7 = 12^(-5 + 7)

Now let's simplify the exponent:

12^(7 - 5) = 12^2

Therefore, the numerical equivalent of 12^(-5) * 12^7 is 12^2.

To find the value of 12^2, we can calculate it as follows:

12^2 = 12 * 12 = 144

So, the numerical equivalent of 12^(-5) * 12^7 is 144.
