Question

Log2=0.3010,log3=0.4771 find log25

Answer 1

I assume that the question is missing log(5).

log(5) = 0.6990

We can factor out log(25) using 5.

log(25) = log(5^2)

Rewrite it using the power rule [ $\text{log}_ax^p = p~\text{log}_ax$ ]

log(5^2) = 2 log(5)

Simplify using the given values.

2(0.6990)

1.3980

Therefore, log(25) = 1.3980

Best of Luck!

Answer 2

Log 5 = 0.6990

log 25 = log 5^2 = 2log 5 = 2(0.6990) = 1.398
