Exp. and Log.

Change to Exponential Form:
log₆36 = 2

• 2⁶=36
• 6²=36
• 36²=6
• 36⁶=2

Change to Logarithmic Form:
5³ = 125

• log ₅ 125 = 3
• log ₃ 125 = 5
• log ₅ 3 =125
• log₁₂₅ 3 = 5

Write in exponential form:

log 1.5051 = 32

• 1.5051 = 32

• 10³² = 1.5051

• 1.5051¹⁰ = 32

• 6

Write in exponential form:
log ₃ 6561 = 8

• 3⁸ = 6561
• 8³ = 6561
• 3⁶⁵⁶¹ = 8
• 8⁶⁵⁶¹ = 3

• D

log₂(x + 5) = 3

• 3
• 4
• 5
• 6

Solve for x:
4^2x + 1 = 17

• x = 1
• x = -1
• x = 2
• x = -2

Solve for x:
e^2x = 11

• x = (LN 11)/2
• x = 2log_e11
• x = 2eLOG 11
• x = LN (11/2)
