Question

Solve: 2^x = 32

x = (blank)^a0

Answer 1

x = ± 4

Explanation:

Given

2x² = 32 ( divide both sides by 2 )

x² = 16 ( take the square root of both sides )

x = ±
`√(16)` = ± 4

Answer 2

1. Take the log of both side:
log2^x = log 32

2. Divide both side:
x= log 2
———
log 32

3. Punch that into a calculator. You should get:

x = 5
