log a = 2
log b = 3
Find log[√(a) / b³]
This requires the use of some log properties. Remember that log(a/b) = log(a) - log(b):
log(√(a)) - log(b³)
Now remember the property of log(a^b) = (b)log(a):
(1/2)log(a) - 3log(b)
Now just plug in the number:
(1/2)(2) - (3)(3)
= 1 - 9
= -8<===Answer
Sorry for the wrong answer earlier.
