9x^{-1/2}=1

Solution

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

Solution

x = 81

Solution steps

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

Expand

9 x^{- \frac{1}{2}} : \frac{9}{x ^{\frac{1}{2}}}

\frac{9}{x ^{\frac{1}{2}}} = 1

Square both sides:

\frac{81}{x} = 1

\frac{81}{x} = 1

Solve

\frac{81}{x} = 1 : x = 81

x = 81

Verify Solutions:

x = 81

True

The solution is

x = 81
