To determine

## To calculate: The simplified form of the expression, |3−|−9||

Expert Solution

The simplified form of the expression is 6 .

### Explanation of Solution

Given information:

The expression , |3|9||

Formula used:

The algebraic identity: |a|=(a)=a .

Calculation:

Consider the expression, |3|9||

Rewrite the expression in the form,.

|3|9||=|3((9))|

Apply the algebraic identity, |a|=(a)=a .

|3|9||=|3((9))|=|39|=(39)=93

As the result is, 93=6

The above expression can’t be simplified further.

Thus, the simplified form of the expression is 6 ..
