x^{- 4} = 81

x = \frac{1}{3}, x = - \frac{1}{3}, x = \frac{1}{3} i, x = - \frac{1}{3} i

Solution steps

x^{- 4} = 81

Refine

\frac{1}{x ^{4}} = 81

Multiply both sides by

x^{4}

1 = 81 x^{4}

Solve

1 = 81 x^{4} : x = \frac{1}{3}, x = - \frac{1}{3}, x = \frac{1}{3} i, x = - \frac{1}{3} i

x = \frac{1}{3}, x = - \frac{1}{3}, x = \frac{1}{3} i, x = - \frac{1}{3} i

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{1}{3}, x = - \frac{1}{3}, x = \frac{1}{3} i, x = - \frac{1}{3} i

ln (1 0^{5}) = - (\frac{1.2}{d})

x - 4 = \frac{5}{x}

\frac{( n + 1 ) !}{( n - 1 ) !} = 56

\frac{x}{x - 2} = 0

\frac{3}{5} = \frac{3}{x}
