Which of the following correctly used the Product Rule of Exponents to simplify the expression 100^8⋅100^7?

A. 200^15

B. 10,000^15

C. 100^15

D. 100^56

5 answers

The correct answer is D. 100^56.

To simplify the expression using the Product Rule of Exponents, you add the exponents when multiplying two numbers with the same base.

In this case, the base is 100, and the exponents are 8 and 7.

So, 100^8 * 100^7 can be simplified as 100^(8 + 7) = 100^15.

Therefore, the correct answer is D. 100^56.

The correct answer is A. 200^15.

To simplify the expression 100^8 * 100^7 using the Product Rule of Exponents, you add the exponents when multiplying two numbers with the same base.

In this case, the base is 100, and the exponents are 8 and 7.

So, 100^8 * 100^7 can be simplified as 100^(8 + 7) = 100^15.

However, 100^15 is not one of the answer choices.

To find the correct answer, we can rewrite 100^8 as (10^2)^8 = 10^(2*8) = 10^16, and rewrite 100^7 as (10^2)^7 = 10^(2*7) = 10^14.

Therefore, 100^8 * 100^7 = 10^16 * 10^14 = 10^(16 + 14) = 10^30.

Since 10^30 is equivalent to (2*5)^30, which then simplifies to 2^30 * 5^30 = (2^3)^10 * (5^3)^10, we can further simplify as 8^10 * 125^10 = (8 * 125)^10 = 1000^10 = (10^3)^10 = 10^30.

Therefore, the correct answer is A. 200^15.

The correct answer is B. 10,000^15.

To simplify the expression 100^8 * 100^7 using the Product Rule of Exponents, you add the exponents when multiplying two numbers with the same base.

In this case, the base is 100, and the exponents are 8 and 7.

So, 100^8 * 100^7 can be simplified as 100^(8 + 7) = 100^15.

Since 100 can be written as 10^2, we have (10^2)^15 = 10^(2*15) = 10^30.

However, 10^30 is not one of the answer choices.

To find the correct answer, we can rewrite 100^8 as (10^2)^8 = 10^(2*8) = 10^16, and rewrite 100^7 as (10^2)^7 = 10^(2*7) = 10^14.

Therefore, 100^8 * 100^7 = 10^16 * 10^14 = 10^(16 + 14) = 10^30.

Since 10^30 is equivalent to (10^4)^3, which then simplifies to 10000^3 = 10,000^3.

Therefore, the correct answer is B. 10,000^15.
