Conjugate Question!

Multiplying this out the long way is tedious, put will give you the correct answer.

You can use the shortcut:  (x + y)⁶  =  x⁶ + 6x⁵y + 15x⁴y² + 20x³y³ + 15x²y⁴ + 6xy⁵ + y⁶

where  x = 3/5  and  y = 4/5·i.           (You can get the coefficients by using either combinations, or Pascal's triangle.)

Finally, find the absolute value of the answer.

Geno maybe that is magnitude?
