Calcule:

$a)$ $5^{ – 1}$ = $ \large \frac{1}{5} $

$b)$ $ (- 3)^{ – 1}$ = – $ \large \frac{1}{3} $

$c)$ $ (- 5)^{ – 2}$ = – $ (\large \frac{1}{5}) ^{2}$ = $ \large \frac{1}{25} $

$d)$ $ (- 10)^{ – 4}$ = – $\large (\frac{1}{10} )^{4}$ = $ \large \frac{1}{10000} $

$e)$ $2^{ – 6}$ = $\large ( \frac{1}{2}) ^{6} $ = $\large \frac{1}{64} $

$f)$ $(0,2)^{2}$= $\large ( \frac{2}{10}) ^{2}$ = $\large ( \frac{1}{5}) ^2$ = $\large \frac{1}{25} $

$g)$ $ 1^{10}$ = $1$

$h)$ $ \large (\frac{13}{3}) ^0$ = $1$

$i)$ $0^{4}=0$

$j)$ $(0,1)^{ – 1}$ = $10$

$k)$ $2^{5} \cdot 2^{2}$ = $2^{ 5 + 2}$= $2^{7}$ = $ 128$

$l)$ $ 3^{5} \div 3^{3}$ = $3^{5 – 3}$ = $3^{2}$

$m)$ $(2^2)^{4}$= $2^{2 \cdot 4}$= $2^8$= $256$
