To add these two numbers, we need to make sure they both have the same exponent.
3.2 x 10^4 can also be written as 32 x 10^3 by moving the decimal point one place to the right.
Now we have:
32 x 10^3 + 1.92 x 10^6
To add these two numbers, we just need to add their coefficients.
32 + 1.92 = 33.92
The result is 33.92 x 10^6.
3.2 x 10^4 + 1.92 x 10^6

3.2 x 10^4 - 1.92 x 10^6
To subtract these two numbers, we need to make sure they both have the same exponent.
3.2 x 10^4 can also be written as 32 x 10^3 by moving the decimal point one place to the right.
Now we have:
32 x 10^3 - 1.92 x 10^6
To subtract these two numbers, we just need to subtract their coefficients.
32 - 1.92 = 30.08
The result is 30.08 x 10^3.
3.2 x 10^4 can also be written as 32 x 10^3 by moving the decimal point one place to the right.
Now we have:
32 x 10^3 - 1.92 x 10^6
To subtract these two numbers, we just need to subtract their coefficients.
32 - 1.92 = 30.08
The result is 30.08 x 10^3.
3.2 x 10^4 x 1.92 x 10^6
To multiply two numbers in scientific notation, we multiply the coefficients and add the exponents.
For example, for 3.2 x 10^4 x 1.92 x 10^6:
The coefficients are 3.2 and 1.92. When we multiply them, we get:
3.2 x 1.92 = 6.144
The exponents are 10^4 and 10^6. When we multiply them, we add the exponents:
10^4 x 10^6 = 10^(4+6) = 10^10
Therefore, the product is 6.144 x 10^10.
For example, for 3.2 x 10^4 x 1.92 x 10^6:
The coefficients are 3.2 and 1.92. When we multiply them, we get:
3.2 x 1.92 = 6.144
The exponents are 10^4 and 10^6. When we multiply them, we add the exponents:
10^4 x 10^6 = 10^(4+6) = 10^10
Therefore, the product is 6.144 x 10^10.
3.2 x 10^4 / 1.92 x 10^6
To divide two numbers in scientific notation, we divide the coefficients and subtract the exponents.
For example, for 3.2 x 10^4 / 1.92 x 10^6:
The coefficients are 3.2 and 1.92. When we divide them, we get:
3.2 / 1.92 = 1.67
The exponents are 10^4 and 10^6. When we divide them, we subtract the exponents:
10^4 / 10^6 = 10^(4-6) = 10^-2 = 1/100 = 0.01
Therefore, the quotient is 1.67 x 0.01, which is equal to 0.0167.
For example, for 3.2 x 10^4 / 1.92 x 10^6:
The coefficients are 3.2 and 1.92. When we divide them, we get:
3.2 / 1.92 = 1.67
The exponents are 10^4 and 10^6. When we divide them, we subtract the exponents:
10^4 / 10^6 = 10^(4-6) = 10^-2 = 1/100 = 0.01
Therefore, the quotient is 1.67 x 0.01, which is equal to 0.0167.
