405=5(9x)^{4/3}

405 = 5 (9 x)^{\frac{4}{3}}

x = 3, x = - 3

Solution steps

405 = 5 (9 x)^{\frac{4}{3}}

Switch sides

5 (9 x)^{\frac{4}{3}} = 405

Divide both sides by

5

(9 x)^{\frac{4}{3}} = 81

Take both sides of the equation to the power of

3 : 6561 x^{4} = 531441

6561 x^{4} = 531441

Solve

6561 x^{4} = 531441 : x = 3, x = - 3

x = 3, x = - 3

Verify Solutions:

x = 3

True

, x = - 3

True

The solutions are

x = 3, x = - 3

2 x - 3 - x + 7 = 4

x - 3 = 2.35

2 = 14.8 \cdot 1 - n

16 x^{2} + 8 = 0
