Question

A= [ 1/2 - ( 1 + 1/2)²] • (2-2/3) e​

Answer 1

Resposta:

-7/3

Explicação passo-a-passo:

[ 1/2 - ( 1 + 1/2)²] × (2-2/3)

[ 1/2 - (1/1 + 1/2)²] × (2/1 - 2/3)

[1/2 - (1×2/1×2 + 1/2)²] × (2×3/1×3 - 2/3)

[1/2 - (2/2 + 1/2)²] × (6/3 - 2/3)

[1/2 - (2+1/2)²] × (6-2/3)

[1/2 - (3/2)²] × 4/3

[1/2 - (3×3/2×2)] × 4/3

[1/2 - 9/4] × 4/3

[1×2/2×2 - 9/4] × 4/3

[2/4 - 9/4] × 4/3

[2-9/4] × 4/3

-7/4 × 4/3

-7×4/4×3

-28/12

-28÷4/12÷4
