To find the Modulus of a complex number
I was given the following expression ,
and was asked to find its value
This is how I proceeded ,
On solving the numerator , the given expression transforms to Then I took the conjugate of the denominator and finally got the expression
Now according to me it’s modulus should be however the correct answer is . Could you please correct me where I am mistaken ? And please suggest a method to solve this. Thank you .
