Answer:
The value of the digit 8 in 80,000 is 10 times the value of the digit 8 in 8,000.
Step-by-step explanation:
When we multiply any number by 10, we add a zero to the end of the number to represent the change in value. The two numbers we are given differ by an extra zero at its end, so we know that the value of the 8's differ by 10 times. From here, we know that 80,000 is larger than 8,000 because 80,000 has more digits (5 compared to 4), so we can conclude that the value of the digit 8 in 80,000 is 10 times the value of the digit 8 in 8,000.
