**Sam**, Thursday, December 30, 2010 at 4:13pmThe question is to evaluate the following.

**Marth**, Thursday, December 30, 2010 at 7:17pmYou can simplify log((a^3)sqrt(ab)/(ab^2)) to log((a^2.5)/(b^1.5)).

= 2.5log(a) - 1.5log(b)

But you cannot evaluate this without knowing log(a) and log(b).

**Sam**, Thursday, December 30, 2010 at 10:01pmshouldnt the answer be simplified to 1.5loga-1.5logb and not 2.5loga ? could u explain why it is 2.5

**drwls**, Friday, December 31, 2010 at 8:06amlog [ a^3(ab)^1/2 / (ab^2) ]

= log (a^2.5 * b^-1.5]

= 2.5 log a - 1.5 log b

Sam is correct. Just use the rules for adding and subtracting exponents when multiplying and dividing.

**Sam**, Friday, December 31, 2010 at 12:31pm1.5loga-1.5logb so this is correct?
