If a = 12, b = -7 and c = -5, then what is the value of $ a^3 + b^3 + c^3 $ ?
Answer & explanation
Correct answer: option 1
If a = 12, b = -7, c = -5,
Then what is the value of $ a^3 + b^3 + c^3 $
If the sum of a + b + c = 0 then the value of $ a^3 + b^3 + c^3 $ = 3abc
Here 12 - 7 - 5 =0
Then , $ a^3 + b^3 + c^3 $ = 3abc = 3 × 12 × -7 × -5 = 1260
