The Cube root of 10 is 1000.
Which means 6^3 /10^3.
i.e 6/10.
So, the correct answer should be 0.6 ( A).

Very sort method.
(216/10^6)^1/3 = (6^3/10^6)^1/3.
= 6^3*1/3/10^6*1/3.
= 6/10^2 = 6/100 = 0.06 Answer.
(216/10^6)^1/3 = (6^3/10^6)^1/3.
= 6^3*1/3/10^6*1/3.
= 6/10^2 = 6/100 = 0.06 Answer.

Because cube root is equal to 1/3.
Like : cube root 9 is equal to 9^1/3.
Got it. Vikas.
