m^{-2}= 1/9

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

m = 3, m = - 3

Solution steps

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

Refine

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

Cross multiply

9 = m^{2}

Solve

9 = m^{2} : m = 3, m = - 3

m = 3, m = - 3

Verify Solutions

Find undefined (singularity) points:

m = 0

Combine undefined points with solutions:

m = 3, m = - 3

\frac{33}{4 + x} = 4

f, \frac{1}{f} = \frac{1}{p} + \frac{1}{q}

\frac{x + 1}{x} = 3^{\frac{1}{2}}

\frac{( a ) ( 7 x - 2 )}{( 4 x )} = 2

\frac{16}{x - 1} = \frac{15}{x - 1}
