then find the number of pairs each number makes .Then from each pair choose one of the numbers and put the other number which does not form pair under square root.

For example-

√8=√(2*2*2)=2√2(then from each pair choose one 2 and put the 2 which does not form pair under square root)

Answer 2

Step-by-step explanation:

simplify (√112-√80)+(√20-√28)

(√112-√80)+(√20-√28)

=4√7-4√5+2√5-2√7

=4√7-2√7 -4√5+2√5

=2√7 - 2√5

=2(√7-√5)

Answer- 2(√7-√5)
