Question

calcule e dê o resultado na forma mais simples:

√64 - (81)⁰,²⁵ + (1/4)⁻¹
__________________________________ =
(-2)³ + 50(0,001)¹/³

Answer 1

[√64-(81)^0,25+(1/4)^(-1)]/[(-2)^3+50.(0,001)^(1/3)]=
[8-(81)^(25/100)+(4/1)^1]/[(-8)+50.(1/1000)^(1/3)]=
[8-(81)^(1/4)+(4)^1]/{-8+50.[raiz cúbica de (1/1000)]}=
[8-(raiz quarta de 81)+4]/[-8+50.(1/10)]=
[8-(3)+4]/(-8+50/10)=
(8-3+4)/(-8+5)=
(9)/(-3)=
-3
