Understanding Exponents and Basic Arithmetic Operations
In mathematics, exponents are a fundamental concept used to represent repeated multiplication of a number. The expression means 5 multiplied by itself zero times, which is equal to 1. Similarly, means 2 multiplied by itself one time, which is equal to 2. When we add these two expressions together, we get .
Evaluating the Options
Now, let's evaluate the given options to determine which one is equal to .

This option is not equal to .
Conclusion
None of the given options are equal to . The correct answer is not among the options provided. However, we can see that the correct answer is simply the sum of and , which is equal to 3.
Tips and Tricks
When evaluating expressions with exponents and basic arithmetic operations, it's essential to follow the order of operations (PEMDAS):
- Parentheses: Evaluate expressions inside parentheses first.
- Exponents: Evaluate exponents next (e.g., ).
- Multiplication and Division: Evaluate multiplication and division operations from left to right.
- Addition and Subtraction: Finally, evaluate addition and subtraction operations from left to right.
Q: What is the order of operations (PEMDAS)?
A: The order of operations (PEMDAS) is a set of rules that tells you which operations to perform first when you have multiple operations in an expression. The acronym PEMDAS stands for:
- Parentheses: Evaluate expressions inside parentheses first.
- Exponents: Evaluate exponents next (e.g., ).
- Multiplication and Division: Evaluate multiplication and division operations from left to right.
- Addition and Subtraction: Finally, evaluate addition and subtraction operations from left to right.
Q: How do I evaluate expressions with exponents?
