Question

resolva a seguinte expressao numerica (1/4) elevado a 0 - (1/4) elevado a -1 + (1/4) elevado a 2

Answer 1

(1/4)⁰ - (1/4)⁻¹ + (1/4)² =
1 - (4/1)¹ + 1/16
1 - 4 + 1/16
MMC = 16
1/1/16 - 4/1/16 + 1/16/1 =
16/16 - 64/16 + 1/16 =
Somando os positivos = 17/16 - 64/16 = - 47/16

Answer 2

(1/4) ^0 - (1/4)^ -1 + (1/4)^2=>

=>1-(4/1)^1+(1/16)

=1-4+1/16

=>-3+1/16

=>-48+1/16

=>-47/16


espero ter ajudado!

bom dia !
