please help guyz I want answer as soon as i will mark you as brainliest and explain please​

Answer 1

Answer:

b. (x⁴-y⁴)

Step-by-step explanation:

(√x+√y)(√x-√y)(x+y)(x²+y²)

Using the property,

(a+b)(a-b)=a²-b²

=(x-y)(x+y)(x²+y²)

=(x²-y²)(x²+y²)

=x⁴-y⁴

Answer 2

Answer:

b)x⁴-y⁴ after solving the equation we get the ans 2

in solution we use the property a²-b²

twice.
