Simplify the mathematical expressions and arrange them in order of their values from least to greatest

See the first attachment. The numbers indicate the order 1=least, 5=greatest.

Step-by-step explanation:

This is a calculator exercise. Put the numbers in your calculator and have it tell you the result. Don't forget that (ab)/(cd) = ab/c/d if you don't use parentheses.

See the 2nd and 3rd attachments for the values of the expressions.

___

You can estimate values as follows (top to bottom):

1. 4·9·10^(8-5) ≈ 36·10^3

2. 7·8·10^(5-2) ≈ 56·10^3

3. (7·9)/(8·4)·10^(5-7+2+3) ≈ 2·10^3

4. (8·10)/(8·6)·10^(4+1-11+8) ≈ 1.7·10^2

5. (2·6)/(3·5)·10^(4+3+2-2) ≈ 0.8·10^7

These are crude estimates, but sufficiently close to put the numbers in order as required.

the answer is b 4pi/3

got it down chief.
