Option C:
The coefficient of  is 40.
 is 40.
Solution:
Given expression:

Using binomial theorem:

Here 
Substitute in the binomial formula, we get

Now to expand the summation, substitute i = 0, 1, 2, 3, 4 and 5.

                                                             
Let us solve the term one by one.






Substitute these into the above expansion.

The coefficient of  is 40.
 is 40.
Option C is the correct answer.
 
        
             
        
        
        
What is m months
i could be able to solve it if i knew what m months were
        
             
        
        
        
Ur answer is c.0.10 because 10 is less than all the other answer choices
        
                    
             
        
        
        
Move negative 4 to the right till you get to positive 3. Then Move negative 3 to the left 4 times
