Question

If A/a=B/b=C/c=D/d; then √Aa+√Bb+√Cc+√Dd/√a+b+c+d.√A+B+C+D

Answer 1

Answer:

Step-by-step explanation:

let,

Then

to find:

substitute in the question

a√x+b√x+c√x+d√x÷√(a+b+c+d)(ax+bx+cx+dx)

=√x(a+b+c+d)÷√(a+b+c+d)[x(a+b+c+d)]

=√x(a+b+c+d)÷√(a+b+c+d)√x√(a+b+c+d)

=√x(a+b+c+d)÷√x√(a+b+c+d)²

=(a+b+c+d)÷(a+b+c+d)

=1
