Ⅰ. √ 500x + √ 402 = 0 Ⅱ. √ 360y + ( 200 ) 1/2 = 0

As per the given above equations , we can say that
Ⅰ.
√500x + √402 = 0
⇒ √500x = - √402
∴ x = - √( 402/500 ) = - √( 400/500 ) = - 0.9
Ⅱ. √360y + ( 200 )^1/2 = 0
⇒ √360y = - √200
∴
y = - √( 200 / 360 ) = - 0.74
Clearly, we can see that x < y is required answer .
