Answer:

Explanation:log(a+b)=log(b*(a/b+1))

log(a+b)=logb +log(a/b+1) …(1)

OR

log(a+b)=log(a*(1+b/a))

log(a+b)=loga+log(1+b/a) …(2)

Let a=1,b=2

Now using eqn 1 to find log(1+2)

log(1+2)=log2+log(1/2+1)

log(1+2)=0.477

Using eqn 2

log(1+2)=log1+log(2/1+2)

log(1+2)=0.477

Well the above two equations are of no use bcoz it increases length of simple calculation .

We can use simple maths 2 solve log(1+2)

log(1+2)=log(3) (adding both numbers)

log(1+2)=0.477 (using log table)

Hope dis may help u
