Solve: 5x^(3/4)- 15 = 0.

Solve for x: x^(5/6) + x^(2/3) - 2x^(1/2) = 0

In Exercises 91–100, find all values of x satisfying the given conditions. y = (x - 5)^(3/2) and y = 125

Exercises 177–179 will help you prepare for the material covered in the next section. If - 8 is substituted for x in the equation 5x^(2/3) + 11x^(1/3) + 2 = 0, is the resulting statement true or false?

Solve each equation. See Example 7. x^3/2 = 125
