Who started the idea of powers?
Powers are just a notational convenience and have been around for a VERY
long time: Diophantus was using an exponent by the 3rd century AD. It was
Descartes (1637) who ". . . put all positive integral powers on the uniform
notational basis familiar today." And Wallis (1655) who started using
fractional and negative powers.
