This code I made includes powers. As for fractions, you'd have to convert those to decimal before passing them to the pow function

Answer 3

Mmm, that's quite a bit more difficult. taking 8^3.14159265 power is hard to do without using a power function. You'd have to create your own, anyway, but it'd be tedious at the least. Why without the built in pow function?

Answer 4

Without built in functions? or does it not matter?

Answer 5

thanks

Answer 6

but without built in functions will be better
