Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=5^2$, $a^m=5^6$, $a=5$, $a^m/a^n=\frac{5^6}{5^2}$, $m=6$ e $n=2$

Simplify $\left(5^{4}\right)^{-2}$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $4$ and $n$ equals $-2$

Applicare la formula: $ab$$=ab$, dove $ab=4\cdot -2$, $a=4$ e $b=-2$
