Question

since comupters were invented, computational speed has multipilied by a factor of 4 about every 3 years. if a typical computer operates with a computational speed s today, write an expression for the speed at which you can expect an equivalent computer to operate after x three year periods

Answer 1

currently: s
after 1 period: 4s
after 2 periods: \[4^2s\]
after x periods: \[4^x s\]
