(4x)/3 x^8=20

\frac{4 x}{3} x^{8} = 20

Solution steps

\frac{4 x}{3} x^{8} = 20

Simplify

\frac{4 x ^{9}}{3} = 20

Multiply both sides by

3

\frac{3 \cdot 4 x ^{9}}{3} = 20 \cdot 3

4 x^{9} = 60

Divide both sides by

4

\frac{4 x ^{9}}{4} = \frac{60}{4}

x^{9} = 15

Rewrite the equation with

u = x^{3}

and

u^{3} = x^{9}

u^{3} = 15

Solve

Substitute back

u = x^{3},

solve for

x

Solve

The solutions are

x^{4} - 4 x^{2} - 45 = 0

x^{4} - 2 x^{3} - 5 x^{2} + 8 x + 4 = 0

3 x^{3} + 81 = 0

16 x^{3} = 54

x^{3} + x^{2} - 2
