Chapter 1: Q5. (page 7)

Evaluate the experssion when $x = 4$
localid="1647946741064" $2 x$

Short Answer

Expert verified

The value of the expression is $8$ .

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 $2 \cdot 3 \cdot 4 = 24$ , 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 $2 x$ , substitute the value of x as 4 and multiply the numbers as shown below,

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

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