1-117.

Write each expression in a simpler form by using the smallest base.

1. $5^{2} · 25^{−3} · 125$

$5^2(5^2)^{-3}(5^3)$

Simplify!

1. $\frac { 9 ^ { 2 } \cdot 3 ^ { - 3 } } { 27 ^ { - 2 } }$

$\frac{(3^2)^{2}(3)^{-3}}{(3^3)^{-2}}$

Simplify!

1. $\left(5 · 14^{98}\right) ÷ \left(8 · 14^{95}\right)$

$\frac{5}{8}(14^3)$

1. $\left(5 · 14^{−98}\right) ÷ \left(8 · 14^{−95}\right)$

$\frac{5}{8}(14^{-3})$
