Use the xth-root function (2nd function of the y^x key, located just above the divide key). For example, to calculate the fifth root of 32, press 3 2 2nd y^x 5 =

Hi,
There is a dedicated key for the function. The key is labeled as on the third line of the table below. You enter a positive number, press the key and then hit [=]. Hope it helps.

You need the [EE] key to enter powers of 10 exponents.
You need the change sign key [+/-] key.
You need the [LOG] key.
pKa: 6.5 [EE] [+/-] 5 [LOG] [+/-]
There are two change sign: The first (either before or after the exponent 5), the last is entered after you press the log key , so as to negate (make negative if result is positive, and make positive is result is negative) the value.
The result should be 4.1870866 or 4.19

You can calculate cube roots by using the cube root function (the 2nd-shift of the 0 key). You can calculate arbitrary roots by using the x-root function (the 2nd-shift of the y^x key, just above the divide key).
