Expand each logarithmic expression completely using the properties of logarithms. Assume all variables are positive.

1. Expand: log₃(xy²)

2. Expand: ln(x³/y)

3. Expand: log(√(x/z))

4. The product rule for logarithms states that logₐ(MN) =  .

5. The quotient rule for logarithms states that logₐ(M/N) =  .

6. The power rule for logarithms states that logₐ(Mᵖ) =  .

7. Which of the following is the correct expansion of log₅(a³b)?

a

3 log₅a + log₅b

b

log₅(3a) + log₅b

c

log₅a + 3 log₅b

d

3(log₅a + log₅b)

8. The expression log(x²/y³) can be expanded as:

a

2logx - 3logy

b

3logx - 2logy

c

log(x²) / log(y³)

d

log(x/y)⁶

9. The expression log₄(x + y) can be expanded to log₄x + log₄y.

T

True

F

False

10. log₇(x/y) = log₇x - log₇y is an example of the quotient rule for logarithms.

T

F

False

11. Expand completely: log₅( (x²y) / z³ )

12. Expand completely: ln( (e⁴x) / (yz²) )
