y^{\frac{2}{3}} - \frac{1}{49} = 0

y = \frac{1}{343}, y = - \frac{1}{343}

Decimal Notation

y = 0.00291 \dots, y = - 0.00291 \dots

Solution steps

y^{\frac{2}{3}} - \frac{1}{49} = 0

Multiply both sides by

49

y^{\frac{2}{3}} \cdot 49 - \frac{1}{49} \cdot 49 = 0 \cdot 49

Simplify

49 y^{\frac{2}{3}} - 1 = 0

Move

1

to the right side

49 y^{\frac{2}{3}} = 1

Divide both sides by

49

y^{\frac{2}{3}} = \frac{1}{49}

Take both sides of the equation to the power of

3 : y^{2} = \frac{1}{117649}

y^{2} = \frac{1}{117649}

Solve

y^{2} = \frac{1}{117649} : y = \frac{1}{343}, y = - \frac{1}{343}

y = \frac{1}{343}, y = - \frac{1}{343}

Verify Solutions:

y = \frac{1}{343}

True

, y = - \frac{1}{343}

True

The solutions are

y = \frac{1}{343}, y = - \frac{1}{343}

2 x - 1 + x = 8
