The Question : PLEASE HELP!!! 25 POINTS. PLEASE NO FAKE ANSWERS
Choose two values, a and b, each between 8 and 15. Show how to use the identity a3 + b3 = (a + b)(a2 − ab + b2) to calculate the sum of the cubes of your numbers without using a calculator.
IMPORTANT: i chose a to be 10 and b to be 12.

So what is the correct answer? Answer:
2728
Explanation:
10^3+12^3=(10+12)(10^2-10*12+10^2)= (12+10)(100-120+144)=(22)(124)=2728

Hope this helps.

Do not hesitate if you need further explanation.
