Question

1)sejam x=(4³)^2:(4^2.4^4)³
e Y= (4^2)³. (4^10:4^8)2^.

determine o valor de:

a) X.Y

b) X:Y
​

Answer 1

Resposta:

a=4^22

b=4^2

Explicação passo-a-passo:

X=4^(3•2) ÷ [4^(2+4)]^3

X=4^6 ÷ 4^(6•3)

X=4^6 ÷ 4^18

X=4^12

Y=4^(2•3) • [4^(10-8)]^2

Y=4^6 • 4^(2•2)

Y=4^6 • 4^4

Y=4^(6+4)

Y=4^10

A=4^12•4^10 = 4^(12+10) = 4^22

B=4^12÷4^10 = 4^(12-10) = 4^2
