Concept explainers
The value of expression

Answer to Problem 21PPE
The value of expression
Explanation of Solution
Given:
The expression
Concept Used:
To evaluate an expression with different operations, an order needs to be followed. The order is first we open the parenthesis then solve exponents then multiply then divide then add then subtract.
This can be remembered using the word PEMDAS - where P stands for Parenthesis, E stands for Exponents, M stands for Multiplication, D stands for Division, A stands for Addition, S stands for Subtraction.
Calculation:
For the expression
Substituting the given values
Therefore, the value of expression
Conclusion:
The value of expression
