me ajudem rapidão pfvr ​

Answer 1

Resposta:

A-

${17}^{1} =$

$17$

B-

${0}^{25} =$

$0$

C-

${10}^{4} =$

$10 \times 10 \times 10 =$

$10000$

D-

${1}^{20} =$

$1$

E-

$( - 0.1)^{3} =$

$( - \frac{1}{10} )^{3}$

$\frac{1}{1000}$

F-

$( - \frac{7}{8} {)}^{2} =$

$( \frac{7}{8} {)}^{2}$

$\frac{ {7}^{2} }{ {8}^{2} }$

$\frac{49}{64}$

Answer 2

$\Large\boxed{\begin{array}{l}\rm a)~\sf 17^1=17\\\rm b)~\sf 0^{25}=0\\\rm c)~\sf10^4=10000\\\rm d)~\sf1^{20}=20\\\rm e)~\sf( -0,1)^3=-0,001\\\rm d)\bigg(-\dfrac{7}{8}\bigg)^2=\dfrac{49}{64}\end{array}}$
