$\bold\red{Question:}$Find the conjugate of $(6+5i)^{2}$

_____ThankU ❤​

Answer 1

(6+5i)² =(6)²+(5i)² +2(6)(5i)

= 36 + 25i² + 60i

= 25i²+60i+36

conjugate of (6+5i)² =( 6-5i) ²...

= 25i²-60i+36......

Answer 2

Hey frnd ,

( 6 + 5i )² = 6² + ( 5i )² + 2 × 6 × 5i

⇒ 36 + 25i² + 60i

⇒ 36 - 25 + 60i

⇒ 11 + 60i

Now conjugate of  11 + 60i is 11 - 60i .

Hope this may help u .
