Question

Calcule as potências: A) (-5)³ B) 1/3 expoente -4     C) 5 expoente 0

D) -1/2 expoente -1 E)   5/6 expoente 4     F) 3 expoente -3

G) 10 expoente -6     H) 10 expoente 6

Answer 1

Bom dia

$A) (-5)^{3} =(-5)(-5)(-5)=-125 \\ \\ B) ( \frac{1}{3} )^{-4} = 3^{4} =81 \\ \\ C) 5^{0} =1 \\ \\D) (- \frac{1}{2} )^{-1} = (-2)^{1} =-2 \\ \\ E) ( \frac{5}{6} )^{4}= \frac{ 5^{4} }{ 6^{4} } = \frac{625}{1296} \\ \\ F) 3^{-3}= \frac{1}{ 3^{3} } = \frac{1}{27} \\ \\ G) 10^{-6} = \frac{1}{ 10^{6} } = \frac{1}{1000000} =0,000001 \\ \\ H) 10^{6}=1000000$

Answer 2

A) (-5)³ = -125

B) $(1/3)^{-4}$ = $(3/1)^4$ = 81/1 = 81

C) $5^0$ = 1

D) $(-1/2)^{-1}$ = $(-2/1)^1$ = -2

E) $(5/6)^4$ = 625/1296

F) $3^{-3}$ = $(1/3^3)$ = 1/27

G) $10^{-6}$ = 0,000001

H) $10^6$ = 1 000 000
