Evaluate the expression when $x = 鈭� 8$
localid="1649144316804" $32 鈭� |x|$

Short Answer

Expert verified

The value of the expressionis 24.

Step by step solution

Step-1 – Absolute value of a number

Absolute value of any positive or negative number is always positive and equal to the magnitude of the number. The absolute value of a number N is denoted by $|N|$ .

The absolute value of a number represents the distance of the number from 0 in the number line.

Step-2 – Example of Absolute value

The absolute value of 3 is denoted by $|3|$ and is equal to 3.

And the absolute value of is denoted by $|鈭� 4|$ and is equal to 4.

Step-3 – Evaluate the expression

To evaluate the value of the expression $32 鈭� |x|$ substitute $鈭� 8$ for x and simplify further as shown below,

$\begin{matrix} 32 鈭� |x| = 32 鈭� |鈭� 8| \\ = 32 鈭� 8 \\ = 24 \end{matrix}$

Thus, the value of the given expression is 24.
