Question

# Find the value of (√5+√5)(√5−√5).\N

Solution

## The correct option is A \NA common tendency to solve this question is to apply the algebraic identity (a2−b2)=(a+b)(a−b). But by observation, we can see that (√5−√5), which is one of the factors, will result in 0, thus making the final value of the whole expression as 0 i.e.  (√5+√5)(√5−√5) =(√5+√5)×(0) =0Mathematics
