Question

Help, please I am so confused.

Answer 1

Answer:

$\frac{1}{ {7}^{14} }$

Step-by-step explanation:

$(7 {}^{2} ) {}^{ - 7}$

Rewrite using power rule

$( {x}^{m} ) {}^{n} = x {}^{m + n}$

$( {7}^{2} ){}^{ - 7} = {7}^{ - 14}$

Now rewrite using the negative power rule,

$x {}^{ - b} = \frac{1}{x {}^{b} }$

${7}^{ - 14} = \frac{1}{ {7}^{14} }$
