11-36.
  1. Solve the equations below. Explain your steps for parts (a) and (c). Check your solutions, if possible. Homework Help ✎

  2. a.

    + 3 = 4

    b.

    (x − 5)3 = 8

    c.

First, isolate the absolute value term.

The value inside the absolute value signs is equal to 1 or −1. Write two equations and solve each of them for x.
x − 3 = 1 x − 3 = −1

What is the cube root of 8?

If you multiply each term by the common denominator, 9, and use Giant Ones, you will eliminate the denominators.
