Question

if underroot m + underroot n- underroot p =0then find the value of ( m+ n -p) whole square​

Answer 1

Answer:

4mn

Step-by-step explanation:

Given :

$\sqrt{m} + \sqrt{n} -\sqrt{p} = 0$

To find : Value of $(m+n-p)^2$

Solution :

$\sqrt{m} + \sqrt{n} -\sqrt{p} = 0$

⇒ $\sqrt{m} + \sqrt{n} = \sqrt{p}$

Squaring both the sides,

We get,

⇒ $(\sqrt{m} + \sqrt{n})^2 = (\sqrt{p})^2$

⇒ $m+n+2\sqrt{mn} = p$

⇒ $m + n + 2\sqrt{mn} - p = 0$

⇒ $m + n - p = -2\sqrt{mn}$

By squarring both the sides,

We get,

⇒ $(m + n - p)^2 = (-2\sqrt{mn})^2 = 4mn$

Answer 2

Answer:

the answer is zero because when we square so we can write like this underroot m + underroot m + underroot n +underroot n -underroot p -underroot p
