Let

$A=(√(2) +√(3) )(√(4) +√(5) )...(√(2020) +√(2021) )\\B=(√(2021) -√(2020) )(√(2019) -√(2018) )...(√(3) -√(2) )$

Answer:

Explanation:

( √(3 ) - √(2) )( √(3) + √(2) )( √(5 ) - √(4) )( √(5) + √(4) )....

using difference of two squares

we can rewrite the A) to 1×1×1×1.... so the answer would be 1
