Question

Let logbA=3 logbC=2 logbD=5

then what is the value of
logb d^2/ c^3a

Answer 1

remember that \[\log_b x = a\]means that \[b^a = x\]

Answer 2

@infamous: You mean: logb (d²/c³a)?

Answer 3

I got c? am I right?

Answer 4

well, let's see:

\[\log_b a = 3\]\[b^3 = a\]\[\log_b c = 2\]\[b^2 = c\]\[\log_b d = 5\]\[b^5 = d\]

\[\log_b \frac{d^2}{c^3a} = \log_b \frac{(b^5)^2}{(b^2)^3(b^3)} = \]
