question is prove by induction on m that m^3 <= 2^m for m=>10

thats supposed to be m cube less than or equal to 2 to the power n for m greater than or equal to 10

P(K)= k^3 less than or equal to 2^k

P(K+1)= (k+1)^3 less than or equal to 2^k+1

2k^3 less than or equal to 2^k+1

(k+1)^3 less than or equal to 2k^3

now im not sure to do next

please help
