The value of the expression is $8$.

See the step by step solution

## Step-1 – Apply the concept of 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 $ab$, substitute the value of a as 4 and the value of b as 2 and multiply the numbers as shown below,

$\begin{array}{l}ab\\ =4\cdot 2\\ =8\end{array}$

Thus, the value of the expression is $8$.
