Question

List the following numbers in order from least to greatest 2.8,2.8x10^2,2.8x10^-3,2.8x10^4,2.8x10^-5

Answer 1

`2.8* 10^(-5),2.8* 10^(-3),2.8, 2.8* 10^2,2.8* 10^4,`

Explanation:

We have been given several numbers and we are asked to order them in least to greatest order.

Given numbers:
`2.8, 2.8* 10^2,2.8* 10^(-3),2.8* 10^4,2.8* 10^(-5)`

We know that the number with negative power will be smaller than the number with positive powers.

We can see from our given numbers that
`2.8* 10^(-5)` has a negative power. We can rewrite this as
`2.8* (1)/(10^5)`. This will be the smallest number.

Upon arranging our given number from least to greatest we will get,

`2.8* 10^(-5),2.8* 10^(-3),2.8, 2.8* 10^2,2.8* 10^4,`

Answer 2

This is the list of the numbers from least to greatest:
2.8x10^-5
2.8x10^-3
2.8
2.8x10^2
2.8x10^4
