Find the conjugates of the following complex number: `((3-2i)(2+3i))/((1+2i)(2-i))`

Text Solution

Verified by Experts

We have given `((3-2i)(2+3i))/((1+2i)(2-i))`
we have to find the conjugate of `((3-2i)(2+3i))/((1+2i)(2-i))`
then
Let a+ib=`((3-2i)(2+3i))/((1+2i)(2-i))`
a+ib=`(3(2+3i)-2i(2+3i))/(1(2-i)+2i(2-i))`
a+ib=`(6+9i-4i-6(i^2))/(2-i+4i-2(i^2))`
Since `(i^2)=-1`
