Final answer:
The student's question required finding arithmetic expressions equal to 25 using different sets of operations. Examples provided show how to combine addition with multiplication, subtraction with division, addition with exponents, and division with exponents to achieve the desired result.
Step-by-step explanation:
The student has asked for arithmetic expressions equal to 25 using different operations. Here are the examples for each case:
- A. Addition and multiplication: 20 + 5 × 1 = 25
- B. Subtraction and division: 50 ÷ 2 - 0 = 25
- C. Addition and at least one exponent: 20 + 5¹ = 25
- D. Division and an exponent: (5²) ÷ 1 = 25
It's important to remember that multiplication or division by the same number on both sides of an equation does not change equality, and enclosing multiple terms in brackets before performing these operations ensures they apply correctly.
