8-98.
  1. Solve each of the following equations. Homework Help ✎

    1. 2(x − 1)2 = 18

    2. 2x + 3 = 10

Divide both sides by 2.
How many solutions are you expecting?

Subtract 3 from both sides.

2x = 7

Take the log of both sides.

log (2)x = log(7)

Apply the Power Property.

x · log(2) = log(7)
