Answer 1

Resposta:

(3/2)^3 - (1/2)^2 x (2/15)^-1

(27/8) - (1/4) x (15/2)^1

3,375 - 1/4 x (15/2)

3,375 - 15/8

3,375 - 1,875

1.5

Answer 2

Resposta:

(3/2) elevado a 3 - (1/2) elevada a 2 × (2/15) elvado a-1

(3/2)³  -(1/2)² * (2/15)⁻¹

3³/2³ -1²/2² *(15/2)

27/8 -1/4 *(15/2)

=27/8 -15/8

=(27-15)/8

=12/8

=3/2
