Answer:

The value of log_6{15} is 1.511.

Step-by-step explanation:

It is given that log_6{30}\approx 1.898 and log_6{2}\approx 0.387.

We have to find the value of log_6{15}.

It can be written as

log_6{15}=log_6\frac{30}{2}

Using property of lo, we get

log_6{15}=log_630-log_62          log_m\frac{a}{b}=log_ma-log_mb

Substitute log_6{30}\approx 1.898 and log_6{2}\approx 0.387 in the above equation.

log_6{15}=1.898-0.387

log_6{15}=1.511

Therefore the value of log_6{15} is 1.511.
