Correct Answer

A

Explanation

X * y + x + y², (2* 3) = (2 + 3²) * 5 = 11 * 5 = 11*5 = 11 + 25 = 36 To find the value of (2*3)*5 using the given equation x*y = x + y², we substitute the values of x and y into the equation.Let's start with (2*3):x = 2y = 3Substituting these values into the equation x*y = x + y², we have:(2*3) = 2 + 3²Simplifying the equation, we get:6 = 2 + 9Combining like terms, we have:6 = 11However, this is not a true statement. Therefore, there is no value of (2*3)*5 that satisfies the equation x*y = x + y².
