Rewrite the expression without the absolute value bars .
| √11 - 7 |
My answer was √11 - 7 but apparently it's wrong someone please help!
Oh wait I understand what my issue was √11 is less than 7 so you'd just switch the two numbers around!
you got it
7 - √11
To rewrite the expression | √11 - 7 | without the absolute value bars, you need to consider two cases.
Case 1: When √11 - 7 ≥ 0
In this case, the expression becomes √11 - 7, which is your original answer.
Case 2: When √11 - 7 < 0
In this case, the expression becomes -(√11 - 7), which can be simplified as 7 - √11.
Therefore, the correct way to rewrite the expression without absolute value bars is:
| √11 - 7 | =
√11 - 7, if √11 - 7 ≥ 0
7 - √11, if √11 - 7 < 0
