Answer 1

Resposta:

A)$5^{3} =125$

B)$10^{5} =100.000$

C)$2^{7} =128$

D)$3^{4} =81$

E)$11^{2} =121$

F)$20^{0} =1$

G)$1,8^{2} =3,24$

H)$0,4^{3} =0,064$

I)$\frac{2^{2} }{3} =1,3$

Answer 2

Resposta:

$a)5^{3} =5.5.5=125$

$b)10^{5} =10.10.10.10.10=100.000$

$c)2^{7} =2.2.2.2.2.2.2=128$

$d)3^{4}=3.3.3.3=81$

$e)11^{2} =11.11=121$

$f)20^{0}=1$

$g)(1,8)^{2} =(1,8).(1,8)=3,24$

$h)(0,4)^{3} = (0,4).(0,4).(0,4)=0.064$

$i)(\frac{2}{3} )^{3} =\frac{2^{3} }{3^{3} } =\frac{8}{27}$

$j)(2,5)^{2} =(2,5).(2,5)=6,25$

$k)(\frac{1}{2} )^{4} =\frac{1^{4} }{2^{4} } =\frac{1}{16}$

$l)(3,7)^{0} =1$
