Compare the numbers in each pair, and give the factor by which the numbers differ. 1.) a. 250 million, 5 billion b. 9.3x10^2, 3.1x10^-2 c. 10^-8, 2x10^-13

(1)

For 250 million:

we know that

so, we can write as

we can also write as

For 5 billion:

we know that

so, we can write as

So, 5 billion is greater than 250 million

Differ factor:

(b)

we can see that

 is greater than

Differ factor:

(c)

we can see that

 is greater than

Differ factor:
