Is ther an easy way to figure this problem out without using trial and error?

If your math (or computer science) book gives you a problem like this, the answer is always going to be an integer. The object of the book is to teach you math, not make your life horrible Smile Start at 2 and work your way up.

(Hint: using this method, it took me about 5 seconds to find the answer)

The answer is 2. 2 to the 10th power is one of the most important numbers to memorize, since it's the number of bytes in a kilobyte of data, or the number of kilobytes in a megabyte, or the number of megabytes in a gigabyte, etc. You'll run into it over and over again in computer science, but as far as I know, there's no easy way to mathematically calculate that if x^10 (or x**10, depending on how you like to represent it) = 1024, x = 2. All you can do is punch in likely numbers until you find it (it's the first number you test, anyway), or use a calculator.
