right bt How did u solve using calculator or by solving ..or orally ?
What kind of calculator do you have?
bu using mind We can solve any cube root in just one second
I'm not sure what you're asking. Do you want to know how to do it with or without a calculator?
please then cube, 300653
the cube of 67 is 300763
No there is condition Cuberoot must be positive integer
ohh, well isn't that convenient
the unit value of an integer will map to a definite unit value when cubed: 0-0 1-1 2-8 3-7 4-4 5-5 6-6 7-3 8-2 9-9 so you know half the number off the hop. which ever 10's cube it lay between is your answer
which is why you guessed wrong when my cube ended in 3
No the main condition is ..I can tell u cube root of that number which is obtained by multiplying three times a number that lie between 1 to 100 and the number which u r multiplying must be positive Integer !
you should list those conditions before hand. either way, neat trick
