Answer:
[tex]2.8\times 10^{-5},2.8\times 10^{-3},2.8, 2.8\times 10^2,2.8\times 10^4,[/tex]
Step-by-step explanation:
We have been given several numbers and we are asked to order them in least to greatest order.
Given numbers: [tex]2.8, 2.8\times 10^2,2.8\times 10^{-3},2.8\times 10^4,2.8\times 10^{-5}[/tex]
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 [tex]2.8\times 10^{-5}[/tex] has a negative power. We can rewrite this as [tex]2.8\times \frac{1}{10^5}[/tex]. This will be the smallest number.
Upon arranging our given number from least to greatest we will get,
[tex]2.8\times 10^{-5},2.8\times 10^{-3},2.8, 2.8\times 10^2,2.8\times 10^4,[/tex]
