Question

I kinda sorta understand this but not completely

Answer 1

Problems 1 - 8.
When you multiply the same number raised to exponents, add the exponents. When you divide the same number raised to exponents, subtract the exponents.

1. $7^{-5} \cdot 7^{3} = 7^{-5 + 3} = 7^{-2}$

3. $\dfrac{2^{7}}{2^{10}} = 2^{7 - 10} = 2^{-3}$
