If ( a×a+1)(a×a+1)÷2a-iota=x+iota y then what is the value of x×x+y×y |
| Answer» First Step :- Rationalise. Second Step :- Squaring both side. Third Step :- Equating real and imaginary parts. (By equating you get value of x^2 - y^2 and 2xy)Then put them in formula. (x^2 + y^2)^2 = (x^2 - y^2)^2 + (2xy)^2 | |
