Answer 1

Resposta:

Explicação passo-a-passo:

Calcule :  

a)10^2  = 10² = 10x10 = 100

b)(-5)^2  = + 5x5 = + 25

c)(-3)^3  = - 3x3x3 = - 27

d)-8^2  = - 8x8 = - 64

e)3^1  = 3

f)(2/5)^2    =2²/5² = 2x2/5x5 = 4/25

g)[(1/2)^2]^3  = (1/2)²ˣ³ = (1/2)⁶ = 1x1x1x1x1x1/2x2x2x2x2x2 = 1/64

h)(-1,2)^2  = + 1,2x1,2 = 1,44

í)(-0,1)^2  = + 0,1x0,1 = 0,01

j)(-2/3)^4 = + 2⁴/3⁴ = 2x2x2x2/3x3x3x3 = 16/81
