Compute ` log_(ab)(root(3)a//sqrtb)" if " log_(ab) a = 4`.

compute log_(3)5log_(25)27

Compute x if log_(x)(0.3) = 3 .

If log_(ab)a=4then log_(ab)((root(3)(a))/(sqrt(b)))=

If log_(a)(ab)=x then log_(b)(ab) is equals to

Show that : log_(a)m div log_(ab)m = 1 + log_(a)b

Prove the following identities: (a) (log_(a) n)/(log_(ab) n) = 1+ log_(a) b" "(b) log_(ab) x = (log_(a) x log_(b) x)/(log_(a) x + log_(b) x) .
