Creating Expressions Using the Digits 5, 6, 7, 8, 9 and the Number 4

Let's create five expressions using the digits 5, 6, 7, 8, 9, and the number 4, along with arithmetic operations.

1. Expression 1: - Using the digit 7 four times and the addition operation, we can create the expression: - 7 + 7 + 7 + 7 = 28

2. Expression 2: - Utilizing the digit 7, the digit 5, and the multiplication operation, we can form the expression: - 7 * 5 = 35

3. Expression 3: - By combining the digit 8, the digit 6, and the subtraction operation, we can construct the expression: - 8 - 6 = 2

4. Expression 4: - Using the digit 9, the digit 5, and the division operation, we can generate the expression: - 9 / 5 = 1.8

5. Expression 5: - Incorporating the digit 9, the digit 5, and the exponentiation operation, we can create the expression: - 9^5 = 59049

These expressions utilize the specified digits and operations to yield the given values.
