Answer:
[tex] \frac{1}{ {7}^{14} } [/tex]
Step-by-step explanation:
[tex](7 {}^{2} ) {}^{ - 7} [/tex]
Rewrite using power rule
[tex]( {x}^{m} ) {}^{n} = x {}^{m + n} [/tex]
[tex]( {7}^{2} ){}^{ - 7} = {7}^{ - 14} [/tex]
Now rewrite using the negative power rule,
[tex]x {}^{ - b} = \frac{1}{x {}^{b} } [/tex]
[tex] {7}^{ - 14} = \frac{1}{ {7}^{14} } [/tex]
