If a = 9.6, b = 4.44 and c = 5.16, then the value of $a^3 − b^3 − c^3 − 3abc$ is: |
0 -1 2 1 |
0 |
a = 9.6, b = 4.44 and c = 5.16 = According to the question = a3 – b3 – c3 – 3abc = (a – b – c )(a2 + b2 + c2 – ab – bc – ac) Now check if a - b - c = 0 then the value of$a^3 − b^3 − c^3 − 3abc$ will be equal to 0 a = 9.6, b = 4.44 and c = 5.16 9.6 - 4.44 - 5.16 = 0 So the value of $a^3 − b^3 − c^3 − 3abc$ = 0 |
