If a = 0.02, b = 0.03, c = -0.05, and a + b + c = 0, find (a3 + b3 + c3) ÷ (3abc)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 1.
a + b + c = 0.02 + 0.03 - 0.05 = 0
If a + b + c = 0 then a3 + b3 + c3 = 3abc
Now, (a3 + b3 + c3) ÷ (3abc)
= (3abc) ÷ (3abc)
= 1
