Consider these three numbers expressed in scientific notation: 8.2 × 10-3, 5.2 × 10-6, and 4.1 × 10-6. which number is the greatest, and by how many times is it greater than the smallest number?

The largest of the three number is  

And smallest number  number is

and it is 2000 times greater than smaller number.

Step-by-step explanation:

Given: The three numbers expressed in scientific notation.

1)

2)

3)  

We have to find the greatest  number and by how many times is it greater than the smallest number.

Consider the given numbers

1) is same as 0.0082

2) is same as 0.0000052

3)   is same as 0.0000041

So the largest of the three number is  0.0082

And smallest number  number is 0.0000041

The Ratio of greatest number to smallest number is

Thus, greater number is 2000 times greater than smaller number.
