localid="1647946693704" $xy$

Short answer

The value of the expression is $72$.

Step-by-step solution

Step 1. Apply the concept of the product.

When two or more numbers are multiplied together, it gives a number. The numbers that are being multiplied are called the factors. And the result of the multiplication of numbers is called the product of those numbers.

Step 2. Example for the product.

In the product $2·3·4=24$, the numbers 2, 3, and 4 are being multiplied to give the product 24. So, the numbers 2, 3, and 4 are the factors in this equation and 24 is the product of the numbers.

Step 3. Evaluate the expression.

To evaluate the expression $xy$, substitute the value of x as 6 and substitute the value of y as 12 and multiply the numbers as shown below,

$\begin{array}{l}xy\\ =6\cdot 12\\ =72\end{array}$

Thus, the value of the expression is $72$.
