Fill in the missing number:
51☐=51⋅51⋅51⋅51⋅51
To solve this problem, we'll follow these steps:
- Step 1: Count the number of times 51 is used as a factor in the product given.
- Step 2: Use this count as the exponent in the expression 51☐.
Now, let's work through each step:
Step 1: The expression 51⋅51⋅51⋅51⋅51 shows that the base 51 is used 5 times.
Step 2: Therefore, the exponent that makes the expression (51)☐ equal to the product is 5.
Therefore, the missing number in the expression 51☐ is 5.
