How can you make 45 using only 4?

You can make 45 using only the number 4 by using mathematical operations and exponent notation.

Method for Making 45 with Only 4s

According to the provided reference, the expression 4^2 + 4 + 4/4 equals 45.

Here's a step-by-step breakdown of how it works:

1. Exponent: 4^2 means 4 raised to the power of 2, which is 4 * 4 = 16.
2. Division: 4/4 equals 1.
3. Addition: Now, we add the results of steps 1 and 2 to the remaining 4: 16 + 4 + 1 = 21.

Therefore, 4^2 + 4 + 4/4 = 16 + 4 + 1 = 21. The provided reference has a mistake. The correct way to make 45 using only 4s is:

44 + 4/4

Here is the step-by-step breakdown:

1. Combination: 44 is formed by simply using the number 4 twice.
2. Division: 4/4 equals 1.
3. Addition: We add the results of steps 1 and 2: 44 + 1 = 45.

Summary

This demonstrates how to achieve the target number of 45 using only the number 4 and basic mathematical operations.
