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
