The power key is marked ^ and is located just above the divide key. For example, to calculate 2 raised to the 7th power, press 2 ^ 7 ENTER

There is no key for the universal root. The operation is available in the MATH MATH menu. For example, to calculate the 7th root of 128, press 7 MATH 5 1 2 8 ENTER

To enter a power of ten, use the *10^x key, located on the bottom row of the keyboard between the decimal point and the Ans keys. For example, to enter 1.2 times ten to the third, press 1 . 2 *10^x 3

To raise a number to a power, use the x^* key, located just below the big round cursor pad, between the x^2 and log keys. For example, to calculate 2 raised to the fourth power, press 2 x^* 4 =

To raise a value to a power, use the ^ key located above the divide key. For example, to calculate 2 raised to the 11th power, press 2 ^ 1 1 ENTER

2 to the 10th power

Use the key labeled times 10 to power X, the one between the decimal dot ant the Ans keys, in the middle of the bottom row of keys.
10 to the power 0 is entered as 1. [x10^X] 9 or simply [x10^X] 9
To enter negative exponents use the change sign key [(-)] just above the [RCL] key
10 to -9 is entered as [x10^X] [(-)] 9 result is shown as 1x10-9.
