Question

Simplify the expression

Answer 1

`\bf ~~~~~~~~~~~~\textit{negative exponents} \\\\ a^(-n) \implies \cfrac{1}{a^n} \qquad \qquad \cfrac{1}{a^n}\implies a^(-n) \qquad \qquad a^n\implies \cfrac{1}{a^(-n)} \\\\ -------------------------------\\\\ 5^(-2)/ 5^4\implies \cfrac{5^(-2)}{5^4}\implies \cfrac{1}{5^25^4}\implies \cfrac{1}{5^(2+4)}\implies \cfrac{1}{5^6}\implies \cfrac{1}{15625}`
