In this question do I add, subtract, or multiply the exponents?

100^12
------
100^8

A.100^96
B.100^4
C.100^20
Thank you

When multiplying/dividing, exponents are added/subtracted respectively.

100^12/100^8 = ?

To find the answer to this question, you need to know a basic exponent rule that states:

When dividing terms with the same base, you subtract the exponents.

So, in the expression (100^12)/(100^8), the base is 100, and the division tells us to subtract the exponents.

Therefore, the answer to this question is:

100^(12-8) = 100^4

Hence, the correct option is B. 100^4.
