# Find the conjugat

Given:

Firstly, we calculate and then find its conjugate

[ i2 = -1]

Now, we rationalize the above by multiplying and divide by the conjugate of 3 + i

…(i)

Now, we know that,

(a + b)(a – b) = (a2 – b2)

So, eq. (i) become

[ i2 = -1]

[ i2 = -1]

Hence,

So, the conjugate of is
