ME AJUDA POR FAVOOOOR

a) [(2)^4]^5=

b) [(1/3)^2]^4 . [(1/3)^3]^2=

c) (0,5)^-3=

Answer 1

Explicação passo-a-passo:

a)

$( { {2}^{4} })^{5} = {2}^{4 \times 5} = {2}^{20}$

b)

$(( { { \frac{1}{3} )}^{2} })^{4} \times ( ({ { \frac{1}{3} )}^{3} })^{2} \\ ( \frac{1}{3} )^{2 \times 4} \times ( \frac{1}{3} )^{3 \times 2} \\ ( \frac{1}{3} ) ^{8} \times ( \frac{1}{3} )^{6} \\ ( \frac{1}{3} )^{8 + 6} \\ ( \frac{1}{3} )^{14}$

c)

$(0.5)^{ - 3} = ( \frac{5}{10} )^{ - 3} = ( \frac{1}{2} )^{ - 3} = {2}^{3} = 8$
