Heya!!

↪ Here's your answer friend,

4/2 + √3 + √7

We have,

4 / ( 2 + √3 + √7)

4 / (2 + √3 + √7) x (2 + √3) - √7 / ( 2 + √3) - √7

==> 4 ( 2 + √3 - √7 ) / ( 2 + √3)² - (√7)²

==> 4 (2 + √3 - √7) / 4 + 4√3 + 9 - 7

==> 4(2 + √3 - √7) / 4√3

==> 2 + √3 - √7 / 4√3

==> 2 + √3 - √7 / 4√3 x √3 / √3

==> 2√3 +3 - √21 / 3

is the required answer.

⭐ Hope it helps you : ) ⭐
