The Exponent Key The exponent key ^ allows you to work out any power. For example: 25   would be entered as  2^5 Press 'ENTER' to get the answer 32. You can use this key to get the power of any number to any exponent. For example: (-3)4    would be entered as  (-3)^4 Press 'ENTER' to get the answer 81. Another example: (2/3)2    would be entered as  (2/3)^2 Press 'ENTER' to get the answer 0.44444444444 Notice the use of brackets to enter negative numbers and fractions. In addition, you can also make the calculator give you a reduced fraction instead of a decimal in the last example. MENU
