Question

if
$\sqrt[?]{ax} - \sqrt[?]{by} \:= b - a$
and
$\sqrt{bx} - \sqrt{ay} = 0$
then value of xxy​

Answer 1

Answer:

Solution to this question has three answers

Sqrt ( x + y ) = Sqrt ( x ) + Sqrt ( y )

Case (1) : when both x & y are zero

Sqrt ( 0+0 ) = Sqrt ( 0 ) + Sqrt ( 0 )

Sqrt ( 0 ) = Sqrt ( 0 ) + Sqrt ( 0 )

☆ 0 = 0 (correct)

Case (2) : when anyone of x , y is zero

Let x=0 & y = b (any natural number)

Sqrt ( 0+b ) = Sqrt ( 0 ) + Sqrt ( b )

Sqrt ( b ) = Sqrt ( 0 ) + Sqrt ( b )

☆ Sqrt ( b ) =Sqrt ( b ) (correct)

Let y=0 & x = a (any natural number)

Sqrt ( a+0 ) = Sqrt ( a ) + Sqrt ( 0 )

Sqrt ( a ) = Sqrt ( a ) + Sqrt ( 0 )

☆ Sqrt ( a ) =Sqrt ( a ) (correct)

Case (3) : when both x & y are not zero

Let x=a=16 & y = b=9 (any natural number)

Sqrt ( a+b ) = Sqrt ( a ) + Sqrt ( b )

Sqrt ( 16+9 ) = Sqrt ( 16 ) + Sqrt ( 9 )

Sqrt ( 25 ) = Sqrt ( 16 ) + Sqrt ( 9 )

5 = 4 + 3
