(v - 7)^{\frac{2}{3}} = 5

v = 5 \cdot 5^{\frac{1}{2}} + 7, v = - 5 \cdot 5^{\frac{1}{2}} + 7

Decimal Notation

v = 18.18033 \dots, v = - 4.18033 \dots

Solution steps

(v - 7)^{\frac{2}{3}} = 5

Take both sides of the equation to the power of

3 : (v - 7)^{2} = 125

(v - 7)^{2} = 125

Solve

(v - 7)^{2} = 125 : v = 5 \cdot 5^{\frac{1}{2}} + 7, v = - 5 \cdot 5^{\frac{1}{2}} + 7

v = 5 \cdot 5^{\frac{1}{2}} + 7, v = - 5 \cdot 5^{\frac{1}{2}} + 7

Verify Solutions:

v = 5 \cdot 5^{\frac{1}{2}} + 7

True

, v = - 5 \cdot 5^{\frac{1}{2}} + 7

True

The solutions are

v = 5 \cdot 5^{\frac{1}{2}} + 7, v = - 5 \cdot 5^{\frac{1}{2}} + 7
