Chapter 1: Q16. (page 24)

Error Analysis Describe and correct the error in evaluating the expression $|- 17|$ .

Short Answer

Expert verified

The correct expression is $|- 17| = 17$ .

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 $- 4$ is denoted by $|- 4|$ and is equal to 4.

Step-3 – Evaluate the expression

The absolute value of $|- 17|$ will be 17 as the distance of -17 is 17 units to the left from 0 on the number line.

So, the correct expression for the given absolute value number is

$|- 17| = 17$

Thus, the correct expression is $|- 17| = 17$ .
