Question

3x9/4-[(2/3)²+2]:9¹(negativo)

Answer 1

Explicação passo-a-passo:

3 × 9/4 - [(2/3)² + 2] : 9⁻¹

3/1 × 9/4 - [(2.2/3.3) + 2] : (1/9)¹

3×9/1×4 - [(4/9) + 2] : 1/9

27/4 - [4/9 + 2/1] : 1/9 ==> mmc(9) = 9

27/4 - [9÷9×4/9 + 9÷1×2/9] : 1/9

27/4 - [4/9 + 18/9] : 1/9

27/4 - [4+19/9] : 1/9

27/4 - 22/9 : 1/9

27/4 - 22/9 × 9/1

27/4 - 22×9/9×1

27/4 - 198/9

6,75 - 22

- 15,25
