3 (- 1)^{\frac{2}{3}} + 2

Solution steps

3 (- 1)^{\frac{2}{3}} - 2 (- 1)

Multiply the numbers:

2 (- 1) = - 2

= 3 (- 1)^{\frac{2}{3}} - (- 2)

Apply rule:

a - (- b) = a + b

3 (- 1)^{\frac{2}{3}} - (- 2) = 3 (- 1)^{\frac{2}{3}} + 2

= 3 (- 1)^{\frac{2}{3}} + 2

2 a (x + 2) - 3 b (x + 2)

3 x + 2 x - 5 = 4 + 6

6 + 63

\frac{2}{3} \cdot 2^{\frac{3}{2}}

- \frac{4}{2 ( - 1 )}
