Question

Evaluate the expression when $y=16\text{and}z=4$.

localid="1649158177320" $yz$

Short answer

The value of the expression is64.

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 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 $yz$, substitute 16 for y and 4 for z in the given expression and multiply the numbers as shown below,

$\begin{array}{c}yz=16\cdot 4\\ =64\end{array}$

Thus, the value of the expression is 64.
