First off, I'd like to begin by saying, I know the quotient rule for exponents. You basically subtract the exponents with the same base, but the problems I've done (shown below) seems to smash this rule. I just need some clarity as to what's going on because these problems just doesn't seem to respect the rule. Thanks in advance.
Problem 1:
W^3 X^6 / W^3 X^-4
Answer : X^10
My Approach:
W^3 X^6 / W^3 X^-4
= X^-4 - X^6
= X^2
---------------------------------------------------------
Problem: 2
6 * 10^3 / 8 * 10^6
Answer: 7.5 x 10^-4
My Approach:
6 * 10^3 / 8 * 10^6
= 0.75 X 10^-3 (I simply divided 6 by 8 and subtracted the exponents)
