  1.    Enter the basewpe16.jpg (3060 bytes)
  2.      Press the ^ key (far right column, below CLEAR).
  3.   Enter the exponent.  If it is an expression, be sure to put it in parentheses.wpe11.jpg (13616 bytes)

  There are special keys for some powers:

  1. To square a number, variable, or expression, enter it, then press the x2 button.
  2. To cube a number, variable, or expression, enter it, then press  MATH-3

    SY01805_.jpg (3274 bytes)    Roots 
    Since roots are just fractional powers, one way is to use the ^ key     and be sure to enclose the fraction in parentheses.

    Roots can also be done with special function keys.

    Square roots:
bulletPress 2nd-x2 to access the square root
bulletEnter the number, variable, or expression.

Cube roots:

bulletPress MATH - 4-ENTER
bulletEnter the number, variable, or expression

Other roots:

bulletEnter the INDEX of the root 
bulletPress MATH - 5 - ENTER

Enter the number, variable, or expression.

example  :  Find the sixth root of 64
