418 written in expanded form is?

Answer 1

you add the #in the hundreds place by the #in the tens place by the #in the ones place

so it would look like this

400+10+8

or if your thinking of scientific expansion you would put the number in a way that is more then 0 but less then 10 and multiply it by ten to the power of the number of decimal places to move over to get the original answer

so it would look like this

4.18*10^2

Answer 2

400+10+8 300+100+18 300+110+8

Answer 3

4.18

Answer 4

400+18

Answer 5

400 + 10 + 8
