Question

1) Calcule as potências
a) 42
b) 4-3 =
c) 51
d) 3-3 =
e) 10 2 =
f) 10-
g) 2-5 =
h) 7 1 =
i) 1-18 =​

Answer 1

Explicação passo-a-passo:

a) 4² = 4 × 4 = 16

b) $4^{-3}$ = 1/4 ×1/4 × 1/4 = 1/64

c) $5^{1}$ = 5

d) $3^{-3}$ = 1/3 × 1/3 × 1/3 = 1/27

e) 10² = 10 × 10 = 100

f) $10^{-1}$ = 1/10

g) $2^{-5}$ = 1/2 × 1/2 × 1/2 × 1/2 × 1/2 = 1/32

h) $7^{1}$ = 7

i) $1^{-18}$ =​ 1/1 × 1/1 × .... (18 vezes isso) = 1
