Did you know?

Did you know that in mathematics, an operation can be defined by a certain formula? For example, the operation "*", in this case, is defined as x*y = x + y + 2xy. Now, let's calculate (2*3)*5 using this operation. First, we substitute the values of x and y in the formula. So, (2*3)*5 becomes (2 + 3 + 2(2)(3))*5. Now, we simplify the expression within the parentheses, giving us (2 + 3 + 12)*5. Further simplifying, we get (17)*5. Finally, multiplying 17 by 5, we find that (2*3)*5 equals 85.
