Hello!
To find the value of a digit, we must first look at its place value. When you're given a number, the place value of the number on the furthest right is 1, and for each number you move left, the place value increases by 10 times.
We're given the number 225,673. If we follow this rule, we see the place value of 3 is 1, 7 is 10, 6 is 100, and 5 is 1000.
Since we know that, we now know that there are 5 1,000s, which would make 5,000.
Therefore, your answer is 5,000.
Hope this helps!
