Evaluate Logarithms

Evaluate the log by thinking " 3 to what power is 1/9" so log₃(1/9) =

• 1/2

• 2

• -2

• 3

Evaluate by thinking 4 to what power is 16, so

log₄16

• 2

• 4

• 1/2

• -2

True or False: log₈64=2

• True

• False

Evaluate log₈ 8 by thinking 8 to what power is 8, so the answer is

• 8

• -1

• 0

• 1

Evaluate log_b(b)

• -1

• 0

• 1

• b

Rewrite 3⁴ = 81 in logarithmic form.

• log₃4 = 81

• log₈₁3 = 4

• log₃81 = 4

• log₄81 = 3
