Given the logarithm expression :
log2 (32)
We need to find the value.
We will assume that the value of log2 (32) = x
Now we will rewrite the equation using the exponent form.
==> log2 (32) = x
==> 2^x = 32
Now we will factor 32.
==> 32 = 2*2*2*2*2 = 2^5
==> 2^x = 2^5
Now we notice that the bases are the same, then the powers should be equal.
==> x = 5
Then the exact value of log2 (32) = 5

We have to find the value of log (2) 32.
Here the base of the log is 2.
We can write 32 as 2^5.
Now for any base log a^b = b*log a and log ( a) a = 1.
So log (2) 32
=> log (2) 2^5
=> 5* log (2) 2
=> 5
Therefore log (2) 32 = 5
We know that if a^y = x, then log(a) = y.
Now let log 2 32 = y.
Then 2^y = 32.
But 2^5 = 32.
So y =5.
Therefore log(2) 32 = 5.
Therefore y = 5, as 2^5 = 32.
