    linux kid, please post your questions in the appropriate forum. Do not use the tutorial subforums for your questions. You've had two previous threads posted in here moved to other places because they didn't belong here. Please take the effort to find the right place to start your threads.

    If you didn't know, all the "^3" means is a number multiplied by itself 3 times. EX- 4^3=64, 6^2=36, 9^5=59049 and so on

    what you're thinking of is different. when you have an exponent, you multiply the larger number by itselfas many times as the exponent says. aka: 1^6 would be 1x1x1x1x1x1, or 1 times itself 6 times. another would be 3^4 which would mean 3 times itself 4 times giving you 3x3x3x3

    so 10^3 would be 10 times itself 10 times. 10x10x10. 10x10 is 100 leaving you with 100x10. 100x10 is 1000, lo and behold there is your answer.

    Larger number? Such terminology could easily confuse the unwary reader.

    By what logic would it be 300 ? Why not 3000 ?
