Question

Упростите выражение, найдите его значение при x = 1 y = 2 плииииз

Answer 1

$(\frac{ x^{2} }{y} - \frac{x}{y^2}) * \frac{xy}{x^2y^2}=\\ \frac{x^2y-x}{y^2}\cdot \frac{xy}{x^2y^2}=\\ \frac{x(xy-1)}{y^2}\cdot \frac{xy}{x^2y^2}=\\ \frac{xy-1}{y^3}\\ \frac{1\cdot2-1}{2^3}=\frac18=0.125$

Answer 2

$( \frac{x^2y-x}{y^2})* \frac{1}{xy}= \frac{x(xy-1)}{y^2}* \frac{1}{xy}= \frac{xy-1}{y^3} \\ \frac{xy-1}{y^3}= \frac{1*2-1}{2^3}= \frac{1}{8}=0.125$

Answer 3

Simplifying the Expression and Finding its Value

To simplify the given expression and find its value when x = 1 and y = 2, we can start by substituting the given values of x and y into the expression and then simplifying it.

The given expression is not explicitly provided, but based on the context, it seems to be a mathematical expression involving x and y. Let's proceed with the simplification and evaluation.

Substituting x = 1 and y = 2 into the expression: x = 1 y = 2

Now, let's simplify the expression and find its value.
