Question

calcule:
a) 1^3 + (1/3)^2 + (1/2)^3
b) 2/5 + (1/2)^2 - 1/10

pfv coloquem o cálculo :) ​

Answer 1

Resposta:

Explicação passo-a-passo:

a) 1^3 + (1/3)^2 + (1/2)^3

=1+1/9+1/8

Mmc(9,8)=72

= (72.1+8.1+9.2)/72

= (72+8+9)/72

= 89/72

________

b) 2/5 + (1/2)^2 - 1/10

=2/5 +1/4 - 1/10

Mmc(4,5,10)=20

= (4.2+5.1-2.1)/20

= (8+5-2)/10

= 11/10
