Log(ab) = Log(a) + Log(b) is the correct formula. According to the laws of logarithm, the logarithm of product of two numbers is equal to the sum of logarithms of two numbers.

If a=10 and b= 1000, then

Log(10*1000) = Log(10) + Log(1000)

Log(10000) = Log(10) + Log(1000)

4 = 1+3


Both the sides are equal so, Log(ab) = Log(a) + Log(b).

Both sides are equal so its Log(ab)=Log(a)+Log(b)

I am not going to do it all out since it is already did out by Amber22
