The value of the expression

Answer to Problem 22CR
Explanation of Solution
Given information:
The expression,
Concept used:
For Order of Operation, we will use PEMDAS rule.
Symbols are representing:
- In the presence of grouping symbols such as parenthesis or bracket, simplify expressions in those first, beginning with the innermost grouping symbol.
- In the expression evaluate exponential expressions or absolute values in order from left to right.
- Divide or multiply in order from extreme left to extreme right.
- Subtract or add in order from extreme left to extreme right.
If there is no grouping symbols or no exponents, we multiply or divide and then add or subtract in the order from left to right.
Calculation:
To simplify the expression
Thus, the value of the given expression is19.
