Qbasic/QuickBasic Programming

Not only can you calculate the LOG of any NUMBER in any BASE, but if you know the NUMBER and the LOG, you can calculate the BASE, and if you know the BASE and the LOG, you can calculate the NUMBER. Therefore, it is easy to calculate any root of a number. For example, the fifth root of 32 = 32 ^ 1/5: BASE is 32; LOG is 1/5 = .2 (converted to decimal). Solve for NUMBER = 2. So for ANY root of ANY number, just use that number as the BASE; calculate the reciprocal of the root as a decimal and use that as the LOG; and the answer will be the ROOT.
