16 x^{4} = 1048576

x = 16, x = - 16, x = 16 i, x = - 16 i

Solution steps

16 x^{4} = 1048576

Divide both sides by

16

x^{4} = 65536

Rewrite the equation with

u = x^{2}

and

u^{2} = x^{4}

u^{2} = 65536

Solve

u^{2} = 65536 : u = 65536, u = - 65536

u = 65536, u = - 65536

Substitute back

u = x^{2},

solve for

x

Solve

x^{2} = 65536 : x = 16, x = - 16

Solve

x^{2} = - 65536 : x = 16 i, x = - 16 i

The solutions are

x = 16, x = - 16, x = 16 i, x = - 16 i

- (a + 1)^{2} (a - 8) = 0

x^{2} + 6 x + 9 = 4 x^{4}

m^{7} - 3 = 0

1400 = 700 (1 + \frac{x}{100})^{5}

\frac{x x ^{8}}{5} = \frac{- 2}{25}
