The place value of each digit in any number increases by ten times as you travel one digit to the left.
For example,the number one is written as 1 . The number 10 has 1 one in the tens place value and this digit 1 represents ten times that of a single 1 in the ones place .
For your question, the 5 in 45000 is worth 10 times the 5 in 4500. The 5 in 45000 is written in the place value one space to the left of the 5 in 4500.
