2=x^{-1/2}

2 = x^{- \frac{1}{2}}

x = \frac{1}{4}

Decimal Notation

x = 0.25

Solution steps

2 = x^{- \frac{1}{2}}

Take both sides of the equation to the power of

- 2 : \frac{1}{4} = x

\frac{1}{4} = x

Switch sides

x = \frac{1}{4}

Verify Solutions:

x = \frac{1}{4}

True

The solution is

x = \frac{1}{4}

4 x + 5 - 2 x + 2 + 1 = 0

\frac{y ^{\frac{3}{2}}}{27} = 1

x - 1 = 19 x + 1

3 y + 4 - y + 9 = 1

(x - 27)^{\frac{3}{2}} = 64
