Question

Calcules as seguintes potências.$a) 4^{-2} \\ b) 2000^{0} \\ c) 1^{400} \\ d) ( -\frac{4}{5} )^{4} \\ e) (-1,3)^{3}$

Answer 1

Boa tarde ^^

A = 

4⁻² = 1/4 x 1/4 = 1/16

B = 

2000° = 1

C = 

1⁴⁰⁰ = 1

D = 

(- 4/5 )⁴ = (- 4/5 ) x (- 4/5 ) x (- 4/5 ) x (- 4/5 ) = (+ 256/625 )

E = 

(-1,3)³ = (- 1,3) x (- 1,3) x (- 1,3) = - 2,197
