√m+√n-√p=0
√m+√n=√p
squaring on both sides
m+2√m√n+n=p
m+n-p= - (2√m√n)
on squaring
(m+n-p)²= 4mn

Someone31: Given that √m+√n-√p=0 adding√p on both sides gives √m+√n=√p

Someone31: Now squaring on both sides for (√m+√n)² use the formula (a+b)²=a²+2ab+b²

Someone31: here a is √m and b is √n

Someone31: (√m+√n)²= (√m)²+2√m√n+(√n)²

Someone31: (√m)²=m and (√n)²=n

Someone31: we get (√m+√n)²=m+2√m√n+n

Someone31: m+2√m√n+n=p

Someone31: subtract p and 2√m√n from both sides

Someone31: we get m+n-p=-(2√m√n)

Someone31: on squaring we get (m+n-p)²= 4mn

Answered by vyas03

given √m+√n = √p
now squaring on both sides
(√m)^2+(√n)^2+2√m*n = (√p)^2
m+n+2√m*n = p
m+n-p = -2√m*n
squaring on both sides we get
(m+n-p)^2 = 4mn
hence the answer is 4mn

kunalwadhwani: pplz write on paper and attach with it
