Question

potência com expoente negativo​

Answer 1

A) (2)⁴= (2).(2).(2).(2)= 8

Answer 2

Resposta:

A) $(2)^{2}$

2.2=4

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

$\frac{1}{2^{2} } =\frac{1}{4}$

C) $(3)^{2}$

3.3=9

D) $(3)^{-2}$

$\frac{1}{3^{2} }= \frac{1}{9}$

E) $(1)^{5}$

1.1.1.1.1=1

F) $(1)^{-5}$

$\frac{1}{1^{5} } =\frac{1}{1}=1$

G) $(10)^{3}$

10.10.10=1000

H) $10^{-3}$

$\frac{1}{10^{3} } =\frac{1}{1000}$

I)$5^{-2}$

$\frac{1}{5^{2} } =\frac{1}{25}$

J) $6^{-3}$

$\frac{1}{6^{3} } =\frac{1}{216}$

K) $1^{-5}$

$\frac{1}{1^{5} } =\frac{1}{1} =1$

L) $(\frac{4}{5})^{-2}$

$(\frac{5}{4} )^{2}$

$\frac{5^{2} }{4^2}$

$\frac{25}{16}$
