Answer 1

\[\huge \frac{b^m}{b^n}=b^{m-n}\]

Answer 2

\[\huge \frac{5^{-4}}{5^3}=5^{-4-3}\]would be step one

Answer 3

so the answer is 5^-1

Answer 4

Answer 8

5^-4/ 5^3

this is actually fairly simple. you figure out the exponents first so its would then be 0.0016/ 125

then divide so it would be 0.0000128
