Question

If √u+√v-√w=0 then find u+v-w

Answer 1

√u+√v=√w,

S.B.S, we get

u+v+2√u.√v =w,

then

u+v-w=2√u.√v,

u+v-w=2√(uv)

Answer 2

Answer:

Step-by-step explanation:

Since, √u + √v - √w = 0

Therefore, √u + √v = √w

Squaring on both the sides,

(√u +√v)² = (√w)²

u + v + 2√uv = w

u + v - w = -2√uv
