Question

Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work. 1/4x3=-27/4​

Answer 1

Answer:

  x = -3

Step-by-step explanation:

One always uses inverse operations to solve an equation.

  1/4x^3 = -27/4

  x^3 = -27 . . . . . . . . . multiply by the inverse of 1/4

  x = -3 . . . . . . . . . . raise each side to the inverse of the power of 3 (in English: take the cube root)
