Chapter 10 Review (with emphasis on Logs)

log₃81 = 

• 2
• 3
• 4
• 5

Rewrite 3⁴ = 81 in logarithmic form.

• log₃4 = 81
• log₈₁3 = 4
• log₃81 = 4
• log₄81 = 3

Rewrite log_pt = m in exponential form.

• p^t = m
• t^m = p
• m^t = p
• p^m = t

log₅25 = ?

• 2
• 5
• 125

Change to Exponential Form:
log₆36 = 2

• 2⁶=36
• 6²=36
• 36²=6
• 36⁶=2

The following:
log ₂ 16 = 4 can be written as...

• 2¹⁶=4
• 4²=16
• 4+4+4+4=16
• 2⁴=16

Change to Logarithmic Form:
12² = 144

• log ₂ 144 = 12
• log ₁₂ 144 = 2
• log ₁₂ 2 = 144
• log ₂ 12 = 144

True or False: log₈64=2

• True
• False

Rewrite in exponential form. log₇(1/49)=-2

• -2⁷=1/49
• 7²=1/49
• 7^-2=1/49
• 7^1/49=-2

log₄1 = 

• 0
• 1
• 4
