However, the numbers it displays depends on the number of decimal places to which you have it set (choice of 0–9 or floating decimal). To set the number of decimal places displayed to three: hit [2ND][FORMAT][3][ENTER]This setting also continues indefinitely (even though the calculator is turned off and on) until it is changed.

SOURCE: is it possible to calculate cube root or higher

To extract the roots of orders higher than 2, you can use the universal power key labeled as [Y to x]. if the exponent is an integer 3, 4, 5, 6 etc.

it gives the cube the 4th power, 5th, 6th, etc.

If the exponent is 1/3, 1/4, 1/5, 1/6 you calculate the cubic root, the 4th root and so on.

When you use it to calculate the roots, the radicand (the number the root of which you are calculating) must be positive, otherwise you may get the result as a complex number.

The syntax of the command is value [Y to x] (1/ order of root)

Ex: cube root of 27 is entered as 27 [Y to x] (1/3)

SOURCE: where is the exponent key on the ba-ii plus

If you mean exponentiation (natural antilogarithm): 2nd e^x (e^x is just to the left of the 7 key).

If you want general powers: y^x (just above the 9 key).

If you want 10^x (common antilogarithm) or simply an [enter exponent] key, there are no keys for those. You'll just have to raise 10 to the desired exponent.
