Question

List the following numbers in order from least to greatest. a) 3.5× 10/3 B) 3.5× 10-2 C) 5.3 × 10/3

Answer 1

`3.5*10^(-2), 3.5*10^3, 5.3*10^3`

B, A, C

Explanation:

This is scientific notation. The numbers
`3.5 * 10^3\\3.5 *10^(-2)\\5.3 * 10^3` can be ordered least to greatest by looking at their digits and exponents. Since a -2 as an exponent is present, this means this is a small decimal and is the least. 3.5 and 5.3 have the same exponent of 3 but 5.3 is greater than 3.5 so its the greatest. The order is

`3.5*10^(-2), 3.5*10^3, 5.3*10^3`
