b^{-2}=0.25

b^{- 2} = 0.25

b = 2, b = - 2

Solution steps

b^{- 2} = 0.25

Refine

\frac{1}{b ^{2}} = 0.25

Multiply both sides by

b^{2}

1 = 0.25 b^{2}

Solve

1 = 0.25 b^{2} : b = 2, b = - 2

b = 2, b = - 2

Verify Solutions

Find undefined (singularity) points:

b = 0

Combine undefined points with solutions:

b = 2, b = - 2

\frac{10}{x} = \frac{5}{7}

\frac{6}{n - 1} + 1 = \frac{6}{n - 1}

5 = \frac{10 + a x}{x}

\frac{1}{- x ^{4}} = 3377024

0 = \frac{c}{1 - v}
