Solving Exponential Equations by Log

Solve for x.

• no solution

• log both sides

• rewrite as an exponential

• nothing, you would not be able to solve it

• divide both sides by 2

Solve for x:  log₆x + log₆(x-5) = 2

• √7

• 9

• 4

• none of these

log (x - 1) - log (x - 2) = log 5

• 7

• 4/9

• 9/4

• 1/7

• 0.489

• 2.552

• 0.893

• 2.044
