How many integers in the list $25,$ $26,$ $27,$ $\dots,$ $250$ are not perfect cubes?
25 thru 250 = 226 numbers
perfect cubes 27 64 125 216 222 are not perfect cubes *** edited*** (oops!)
do you mean 222?
Yes, EP means 222, and you mean 'thanks' :)
250-25+1=226 numbers in total
25^(1/3) = 2.924017738212866
250^(1/3) = 6.299605249474365
so only 3cubed, 4 cubed, 5 cubed and 6 cubed will be perfect cubes. There is 4 of them
You can finish it.
