If a=9, b= -5 and c= -4, then find the value of $$a^3+b^3+c^3$$​​

Correct option is D

Given: 

a = 9, b = -5 and c = -4, 

​$$a^3+b^3+c^3$$ = ?​

Solution:

​$$a^3 = 9^3 = 729$$ 

$$b^3 = (-5)^3 = -125$$ 

$$c^3 = (-4)^3 = -64$$

Now, summing these values:

​$$a^3 + b^3 + c^3 = 729 + (-125) + (-64)$$

$$a^3 + b^3 + c^3 = 729 - 125 - 64$$ 

$$a^3 + b^3 + c^3 = 729 - 189 = 540$$ 

Thus, the value of $$a^3 + b^3 + c^3 = 540$$ .​
