• Multiply both sides by 4

• Divide both sides by 5

Multiple Choice

Let's practice some more.

 $2\left(3\right)^k=162$  
First we have to ____________

• isolate the exponential 

• multiply 2 and 3

Multiple Choice

How do we isolate the exponential part in this equation?

 $\frac{1}{2}\left(7\right)^x=171.5$  

• Divide both sides by 2

• Multiply both sides by 2

Poll

Which would you rather do to isolate the exponential in the equation

 $\frac{2}{3}\left(3\right)^x=18$ ? 

• multiply both sides by the reciprocal of 2/3

• multiply both sides by 3, then divide both sides by 2
