Answer:
Given,
√m + √n - √p = 0
To find,
The value of (m+n-p)².
Solution,
The value of (m+n-p)² will be 4mn.
We can easily solve this problem by following the given steps.
According to the question,
√m + √n = √p (Moving √p from the left-hand side to the right-hand side results in the change of the sign from minus to plus.)
Now, square on both sides,
(√m + √n)² = (√p)²
Using the identity (a+b)² = a²+b²+2ab,
(√m)² + (√n)² + 2 √mn = p
m+n+2√mn = p
m+n-p+2√mn = 0
m+n-p = -2√mn
(m+n-p)² = (-2√mn)²
(m+n-p)² = 4mn
Hence, the value of (m+n-p)² is 4mn.
