Question

What do you do when you divide two numbers written in exponential notation?

A. Add the exponents of the 10 together
B. Multiply the exponents of the 10 together
C. Subtract one exponent of the 10 from the other
D. Divide one exponent of the 10 by the other

I think the answer is D, is that correct??

Answer 1

nope. Subtract the exponents.

10^7/10^3 = (10^3 * 10^4)/10^3 = 10^4

or, more brute-force,

10*10*10*10*10*10*10
-------------------------- = 10*10*10*10
10*10*10

Answer 2

Ok, so then the correct answer is C?
