x^{\frac{2}{5}} = 243

x = 5314413, x = - 5314413

Decimal Notation

x = 920482.81322 \dots, x = - 920482.81322 \dots

Solution steps

x^{\frac{2}{5}} = 243

Take both sides of the equation to the power of

5 : x^{2} = 24 3^{5}

x^{2} = 24 3^{5}

Solve

x^{2} = 24 3^{5} : x = 5314413, x = - 5314413

x = 5314413, x = - 5314413

Verify Solutions:

x = 5314413

True

, x = - 5314413

True

The solutions are

x = 5314413, x = - 5314413

x, y = 7 + 49 - x^{2}

25 x^{2} + 100 x + 125 = 5

x - (x + 1) = 1

(v - 8)^{\frac{2}{3}} = 2
