Answer: Look below for explanation...
Step-by-step explanation: Algebra rules for absolute values are listed below.
Piecewise Definition:|a|={aifa≥0−aifa<0|a|={aifa≥0−aifa<0
Square root definition:|a|=√a2|a|=a2
Rules:
1. |–a| = |a|2. |a| ≥ 0 3.
Products: |ab| = |a||b| 4.
Quotients: |a / b| = |a| / |b| 5.
Powers: |an| = |a|n6.
Triangle Inequality: |a + b| ≤ |a| + |b| 7.
Alternate Triangle Inequality: |a – b| ≥ |a| – |b|
PLEASE BE CAREFUL!! Sums: |a + b| is not the same as |a| + |b| Differences: |a – b| is not the same as |a| – |b|
