Evaluate each expression if $m = 鈭� 8, n = 4,$ and $p = 鈭� 12$ .
$鈭� 3 |6 n 鈭� 2 p|$

Short Answer

Expert verified

The value of the expression is $鈭� 144$ .

Step by step solution

Step 1. Plug the values of the variables.

A variable is a letter or a literal used to signify an unknown quantity.

We are given the expression $鈭� 3 |6 n 鈭� 2 p|$ and $m = 鈭� 8, n = 4,$ , plugging these values:

We get:

$\begin{array}{l} 鈭� 3 | 6 n 鈭� 2 p | \\ = 鈭� 3 | 6 脳 4 鈭� 2 (鈭� 12) | \end{array}$

Step 2. Simplify the expression.

$\begin{array}{l} 鈭� 3 | 6 脳 4 鈭� 2 (鈭� 12) | \\ = 鈭� 3 | 24 + 24 | \\ = 鈭� 3 | 48 | \end{array}$

Step 3. Apply the definition of absolute function.

The absolute value or modulus of a real number x, denoted $|x|$ , it is the non-negative value of $x$ without regard to its sign.

$|x| = x$ if is $x$ positive,

$|x| = 鈭� x$ if $x$ is negative,

$|0| = 0$ .

For example, the absolute value of 5 is 5, and the absolute value of 鈭�5 is also 5.

We have the expression $鈭� 3 | 48 |$ , now using definition of absolute value function we get:

$\begin{array}{l} 鈭� 3 | 48 | \\ = 鈭� 3 脳 48 \\ = 鈭� 144 \end{array}$

Thus, the value of the expression is $鈭� 144$ .
