Question

Simplify: (√x - √y ) (√x + √y ) (x + y) (x2 + y2 )

Answer 1

Answer:

x^4-y^4

Note

^ is "to the power"

Step-by-step explanation:

(√x - √y ) (√x + √y ) (x + y) (x^2 + y^2 )

√x^2 - √y^2 (x + y) (x^2 + y^2 )

(x-y) (x+y) (x^2 + y^2)

x^2-y^2 (x^2 + y^2)

(x^2)^2 - (y^2)^2

x^4-y^4

Answer 2

Answer:

I actually didn't understood whether the last bracket was ......don't worry the last bracket will remain untouched and the ans. will be the last bracket.....here I have did as x*2 + y*2

the above ans. is wrong

because in 3rd step the *2 and√ will get cancelled
