Can someone tell me how the logarithm tables were found? Well, I know they are simple for numbers which are multiples of 10 but what about numbers like 2,5 ,0.01 etc.? For example, we know that log 10 = 1 and log 100 = 2, it is simple because we know that 10 ^1 = 10 and 10^2 = 100  but how do we calculate 10^x = 2 ,in other words log 2 = x ( I don t know the answer). The problem is that 2 is not an integral mutiple of 10 so how were these tables calculated ?
