Question

X Square by Y Square minus 10X by Y plus Y Square by X Square find the square root of the expression

Answer 1

Answer:

x2/y2-10x/y+y2/x

I think your question is your answer. It is because when we square of any number this the number's double number. And when we sqrt that, the number remains the previous answer.

Answer 2

Answer:

$\frac{ {x}^{2} }{ {y}^{2} } - \frac{10x}{y } + \frac{ {y}^{2} }{ {x}^{2} } \\ = \frac{ {x}^{4 } - 10 {x}^{3} y + {y}^{4} }{ {x}^{2} {y}^{2} } \\ = \sqrt{( \frac{ {x}^{4} - 10 {x}^{3} y + {y}^{4} }{ {x}^{2} {y}^{2} } } )^{2} \\ = \frac{ {x}^{4} - 10 {x}^{3} y + {y}^{4} }{ {x}^{2} {y}^{2} }$
