Let's use FOIL (first, outer, inner, last) to solve this. We'll multiply the terms by one another in that fashion.

Rearrange in decreasing exponents.

 
        
             
        
        
        
From least to Greatest: 8/100, 7/10, 3/5
        
                    
             
        
        
        
Answer:
<em>C.</em> 
Step-by-step explanation:
Given

Required
Determine which binomial expansion it came from
The first step is to add the powers of he expression in brackets;


Each term of a binomial expansion are always of the form:

Where n = the sum above

Compare  to the above general form of binomial expansion
 to the above general form of binomial expansion

Substitute 6 for n

[Next is to solve for a and b]
<em>From the above expression, the power of (5) is 2</em>
<em>Express 2 as 6 - 4</em>

By direct comparison of 

and 

We have;

Further comparison gives



[Solving for a]
By direct comparison of 



[Solving for b]
By direct comparison of 


Substitute values for a, b, n and r in
