Could someone remind me how to calculate this on the TI84 Calculator:
Which buttons do I hit for this:
3 * 10^8/5.4 * 10^14 I'm inputting it and coming up with 5.55 E 21
It should come out to be 5.55 *10^7 but I'm not doing the input correct
Please help

Physics help on the TI84 calculator 
Joe,
(3*2nd+8)/(5.4*2nd+14)
