Here are the results for the expressions:

1. First expression: \( 1.0 \) ✔
2. Second expression: \( -1.0 \) ✘
3. Third expression: \( 0.25 \) ✘
4. Fourth expression: \( 1.0 \) ✔
5. Fifth expression: \( 13.0 \) ✘

Thus, the correct answers are the **first** and **fourth** expressions, which are equal to 1.

Would you like any further explanation or details on these calculations?

Here are some follow-up questions you might find helpful:
1. How is fractional multiplication applied in the first expression?
2. What causes the second expression to result in a negative number?
3. Can you explain how order of operations affected the third expression?
4. Why does the fourth expression result in exactly 1?
5. What is the role of exponents in simplifying the fifth expression?

**Tip:** When solving complex expressions, always apply the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) carefully.

Select all of the expressions that are equal to 1.

Learn how to solve expressions involving fractions, exponents, and algebraic operations. This problem teaches the application of the order of operations to determine which expressions equal 1. Suitable for Grades 9-12.
