Question

Xy+y²/5 * 11/x+y при x=0; y=15

Answer 1

У(х+у)/5*11/х+у=11у(х+у)/5(х+у)=11у/5=11*15/5=11*3=33

Answer 2

To evaluate the expression xy + y²/5 * 11/x + y at the given values x=0 and y=15, we simply substitute these values into the expression and perform the calculations step by step.

Let's do the calculations:

Step 1: Substitute x=0 and y=15 into the expression xy + y²/5 * 11/x + y = 0*15 + (15²/5) * 11/0 + 15

Step 2: Simplify the expression = 0 + (225/5) * 11/0 + 15

Step 3: Divide by zero error Since the expression involves division by zero (11/0), it is undefined. Division by zero is not allowed in mathematics, and therefore, the expression is undefined when x=0.

So, the expression xy + y²/5 * 11/x + y is undefined when x=0 and y=15.
