To evaluate: the expression |100| .

Expert Solution

Answer to Problem 65E

  |100|=100

Explanation of Solution

Given information:

An expression is given as |100| .

Formula used:

Absolute value property:

For any real number a,

  |a|=a0|a|=|a|=a

Calculation:

Consider the given expression.

  |100|

Now, compare the expression with |a| :

  |a|=|100|a=100

Now, by absolute value property:

  |a|=a0

Therefore, |100|=100

(b)

To determine

To evaluate: the expression |73| .

Expert Solution

Answer to Problem 65E

  |73|=73

Explanation of Solution

Given information:

An expression is given as |73| .

Formula used:

Absolute value property:

For any real number a,

  |a|=a0|a|=|a|=a

Calculation:

Consider the given expression.

Now, compare the expression with |a| :

  |a|=|73|a=73

Now, by absolute value property:

  |a|=|a|=a

Therefore, |73|=73
