Practice with Properties of Logarithms



Practice with Properties of Logarithms

For #1 – 7, use properties of logarithms to solve each equation.

1) log 4t + log t = log 36 2) log t + log (t – 4) = log 12

3) log 12k – log 4 = log 15 4) log 8y2 – log 2y = log 8

5) 2 log y = log 4 + log (y + 8) 6) 2 log (2y + 2) = log 16 + 2 log (y – 2)

7) [pic]log (c + 1) + [pic]log (c – 4) = log 6 8) If log 2 = 0.3010 and log 5 = 0.6990, what is log 20? (Use the values of log 2 and log 5 to determine the answer.)

8) Prove:

log (x2 – y2) – log (x + y)2 = log (x – y) – log (x + y)

9) Prove:

[pic]
