Expressions log 2-log 4 is equal to b) log(1/2)
What is logarithm?
The exponent or power to which a base must be raised to yield a given number . example : If x is the logarithm of n to the base b then
b ^x = n , we can write it as
x= log(base b) * n
since ,log a - log b = log (a/b)
hence, log (2) - log (4) = log (2/4) = log (1/2)
answer is option b) log(1/2)
