Logarithm Rewrite, Evaluate and Property Review

Rewrite the equation into logarithmic form:
6² = 36

• log₆ 2 = 36
• log₆ 36 = 2
• ln 36 = 2
• 6³⁶ = 2

To evaluate a logarithm statement log₉81, you think "9 to what power is 81".

• True, and it's 2

• False

Evaluate the log by thinking " 3 to what power is 1/9" so

log₃(1/9) =

• 1/2

• 2

• -2

• 3

Re-write in log form 2⁶=64

• log₂6=64
• log₂64=6
• log₆₄2=6
• log₆₄6=2

The base of common log is 10.

• TRUE

• FALSE

• You never taught us that!!!!

• Wait. Wut?

Condense:

(log 3 - log 6) + log 2

• log 4

• log 2

• log 1

• log 6

Expand the logarithm expression

log 5x/4y

• log 5x + log 4y

• log 5x - 4log y

• (log 5 + log x) - (log 4 + logy)

• 5log x - 4 logy

Condense:

log₄60 - log₄4 + log₄x

• log₄15

• log₄15x

• log₄56x

• xlog₄30

Evaluate.
log(1/100)

• –2
• 1/2
• –1/2
• 2

Solve the equation.
4^x+1 = 8^2x–3

• x = –7/4
• x = –4/11
• x = 11/4
• x = 7/11
