What is the value of log 375 + 2 log v5 - 3 log 13?
Given that, log 2 = 0.3012, log 3 = 0.4771 and log 5 = 0.6989​

Answer 1

For 375, you can write it as 125 * 3, now 125 is 5 power 3. So, log 375 = log 125*3 = log 125 + log 3.

As 125 is 5 power 3, log 125 = 3 log 5.

2 log √5 = log 5.

At the end you have to add all this to het the final answer.

In last term there is some mistake I think.
