Answer:
Remember, the expansion of
.
Then,

a) since
, then
. Therefore, the coefficient of
is 
b)
. Then k=5 and the coefficient of the term is 
c)
, then k=4 and the coefficient of the term is 
Step-by-step explanation:
So you would need to find a common denominator to add the fractions together first, and the closest would be 40
5/8 turns into 25/40 because we times the bottom and the top by 5 to get the LCD (least common denominator)
6/10 turns into 24/40 when times by 4 for the LCD of 40
Then add them together: 25/40 + 24/40 = 49/40
And since 1 could also be written as 40/40 since that is the whole number, this means the following expression is true.
49/40 > 40/40 (or 1)
