Answer 1

Step-by-step explanation:

(4) ² + ( /5)² +2 ( 4 +/5y)

16 +5 y²+8 +2/5y

24 +5y² + 2root 5 y .....

hopefully helping you...

Answer 2

➡ (4 + √5y)²

• (a + b)² = a² + b² + 2ab

➡ (4)² + (√5y)² + 2(4)(√5y)

➡ 16 + 5y² + 8√5y

$\underline{\boxed{\bf{\purple{∴ (4 + \sqrt{5}y)^{2} = 16 + 5y^{2} + 8\sqrt{5}y}}}}</p><p>$
