8-98.

Solve each of the following equations.

$2\left(x − 1\right)^{2} = 18$
Step 1(a):
Divide both sides by 2.
How many solutions are you expecting?

$2^{x} + 3 = 10$
Step 1(b):
Subtract 3 from both sides.
2^x = 7
Step 2(b):
Take the log of both sides.
log (2)^x = log(7)
Step 3(b):
Apply the Power Property.
x · log(2) = log(7)
