Question

Expand each logarithm:

log (a*b)^2
log (3*2^3)
log u^4/v

Answer 1

Log rules:
Log a ^ b = b Log a
Log(ab) = Log a + Log b
ex (1):
log(ab)^2 = 2lob(ab) = 2log(a) + 2 log(b)

Answer 2

so the expanded answer is 2log(a) + 2 log(b)?

Answer 3

Yeah, expand the second yourself and I will check your answer.

Answer 4

Note : Log b - log a = log b/a
