Question
Simplify and express the result in power notation with positive exponent: ${\left( {\frac{1}{{{2^3}}}} \right)^2}$
✓
Answer
${\left( {\frac{1}{{{2^3}}}} \right)^2}$
$ = \frac{{{1^2}}}{{{{({2^3})}^2}}}$
$ = \frac{1}{{{2^{3 \times 2}}}}$
$ = \frac{1}{{{2^6}}}$
$ = \frac{{{1^2}}}{{{{({2^3})}^2}}}$
$ = \frac{1}{{{2^{3 \times 2}}}}$
$ = \frac{1}{{{2^6}}}$
