3 x^{2 - 5} = 81

x = \frac{1}{3}, x = - \frac{1}{6} + \frac{1}{2 3} i, x = - \frac{1}{6} - \frac{1}{2 3} i

Solution steps

3 x^{2 - 5} = 81

Expand

3 x^{2 - 5} : \frac{3}{x ^{3}}

\frac{3}{x ^{3}} = 81

Multiply both sides by

x^{3}

3 = 81 x^{3}

Solve

3 = 81 x^{3} : x = \frac{1}{3}, x = - \frac{1}{6} + \frac{1}{2 3} i, x = - \frac{1}{6} - \frac{1}{2 3} i

x = \frac{1}{3}, x = - \frac{1}{6} + \frac{1}{2 3} i, x = - \frac{1}{6} - \frac{1}{2 3} i

\frac{( 4 k - 10 )}{k} = 8

\frac{36}{x} = 4

x - 20 = \frac{5}{6 x}

\frac{1}{x} = 0.003

\frac{2 x}{x + 2} = \frac{2 x - 3}{x}
