sqrt5

Explanation:

Split the root so there is a separate numerator and denominator.

sqrt5/sqrt4 + sqrt10/sqrt(4xx2)

=sqrt5/2 + sqrt10/(2sqrt2) " find LCD"

=(color(red)(sqrt2xxsqrt5) + sqrt10)/(2sqrt2)

=(color(red)(sqrt10)+ sqrt10)/(2sqrt2)

=(cancel2sqrt10)/(cancel2sqrt2)

=(sqrt2 xxsqrt5)/sqrt2

=sqrt5

Nice!!
