Question about Texas Instruments BA-II Plus Calculator

To raise a value to a power, use the y^x key located just above the 9 key. For example, to raise 2 to the third power, press 2 y^x 3 =

Unlike most calculators, there is no dedicated key for decimal exponents. You will have to use the above procedure to raise 10 to an exponent.

If you do not have the Enter Exponent key (EE) you can use the general power key marked [Y^x], the one above the [9] key. Use parentheses to enclose the (10^23) and (10^28).

Frankly, if you have to do many calculations of this kind, better buy yourself a scientific calculator.

Break the problem up into smaller pieces.

There's a limit to how big a number the calculator can represent. Numbers as large as 10 times 10 to the 100 simply can't fit into the calculator. For really large numbers, calculate the mantissa and the exponent (power) separately.

For example, to calculate 2^360, first calculate 2^300: press 2 ^ 3 0 0 = and see 2.037036*10^90. Divide by 10^90 (and remember the 90): / 1 0 y^x 9 0 = and see 2.04. Multiply by 2^60: * 2 ^ 6 0 = and see 2.348543*10^18. Multiply that by the 10^90 we took out earlier by adding exponents and write down 2.348543*10^108. That number is too large to fit into the calculator but we got it by calculating the 2.348543 and the 108 separately.

The same way you raise a number to a non-fractional power, using the y^x button. For your example, press

3 y^x ( 1 / 1 2 ) =

or

3 y^x 1 2 1/x =

3 y^x ( 1 / 1 2 ) =

or

3 y^x 1 2 1/x =

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)
