consider 64r^15+343. rewrite 64r^15+343 as (4r^5)^3+7^3. THE SUM OF CUBES CAN BE FACTORED USING THE RULE a^3+b^3=(a+b) (a^2-ab+b^2)
(4r^5+7)(16r^10-28r^5+49)
Rewrite the complete factored expression. The following polynomials are not factored since they do not have any rational roots: (4r^5+7)(16r^10-28r^5+49)

Answer:
FACTOR 10s(4r^5+7) (16r^10-28r^5+49)
evaluate: 10s(64r^15+343)
Step-by-step explanation:
640r^15s+3430s
factor out 10
10(64r^15s+343s)
consider 64r^15s+343s. factor out s
s(64r^15+343)
