Solve:

2log₆(x-8)=2

(a)  

• log both sides

• rewrite as an exponential

• nothing, you would not be able to solve it

• divide both sides by 2

2log₆(2x + 3) - 5 = 1

(a)  

The first step to solve 8 + log 7 = 10 is...

• Rewrite exponentially

• Subtract 8 on both sides to isolate the log

• Divide by 7 on both sides
