Read each question carefully and apply the appropriate logarithm rule to solve. Show all your work for full credit.

1. The Product Rule states that log_b(MN) =  .

2. The Quotient Rule states that log_b(M/N) =  .

3. The Power Rule states that log_b(M^p) =  .

4. The Change of Base Formula allows us to write log_b(M) as  .

Expand the following logarithmic expressions:

5. log_2(8xy)

6. log_3(x^5 / y^2)

7. ln(√(ab))

Condense the following logarithmic expressions into a single logarithm:

8. log(x) + log(y) - log(z)

9. 3ln(a) + 2ln(b)

10. (1/2)log_5(x) - 4log_5(y)

11. Which expression is equivalent to log_b(x^3 * y)?

a

3log_b(x) + log_b(y)

b

log_b(3x) + log_b(y)

c

log_b(x^3) * log_b(y)

d

log_b(x) + 3log_b(y)

12. If log_10(5) ≈ 0.699 and log_10(2) ≈ 0.301, what is log_10(100)?

a

0.301

b

0.699

c

1

d

2

13. Given log_a(x) = 2 and log_a(y) = 3, find log_a(x^2 * y^3 / a).
