LOGS, EXPONENTIALS AND STUFF

Solve for x:

2^{3x - 1} = 32

• 0

• -1

• 5/3

• 2

Solve: 9^8-x = 27^x-3

• x = 5
• x = -5
• x = 1/5
• x = -1/5

2^x - 5 = 12

• x = 8.5

• x = 4.1

• x = 6.2

• x = 3.9

Use a LOG to solve the exponential function.  
2^x-1 + 5 = 20

• x = 3.91
• x = -0.46
• x = 4.91
• x = 5.31

Expand: log (x²y³)

• 2log x - 3 log y

• 3log x + 2 log y

• 6 log xy

• 2log x + 3 log y

Simplify:

• 2
• 8
• 16
• 32
