The nth root of a number is that number which when raised to the nth power (ie when multiplied by itself n times) results in the number.
When n=2, it is the square root of the number;
when n=3 it is the cube root of the number.
To find the nth root of a number, an electronic calculator can be used, using the nth root button [x√y] (though more recent calculators replace the x and y by boxes) viz:
<n> [x√y] [2] [4] [4] [=]
or with the more recent calculators:
[#√#] <n> [Navigate →] [2] [4] [4] [=]
where <n> is the nth root, eg for 2nd root (square roots) enter [2];
and the # is being used to represent a box on the keys of the more recent calculator.
Considering the rules for indices, the nth root is the the number to the power of 1/n, ie 244^(1/n), thus the calculation can be done using the power button:
[2] [4] [4] [^] [(] [1] [÷] <n> [)] [=]
With the more recent calculators, the power button is pressed first, the 244 entered, the navigate-right key pressed (to get in to the power part of the input) and then the n entered.

That will depend on what "n" is.You can calculate any root in Excel (among others) with the power operator; for example, if you want the third root of 244, you type in the formula:
=244^(1/3)
That is, 244 to the power 1/3.
yes the nth root of zero is always zero
Assuming that you mean the nth. root: two - a negative and a positive root.
rearrange the following: A^(1/n)= the nth root of A. eg A to the power 1/2 equals the square root of A. A to the power 1/3 equals the cube root of A. etc.
10 squared is 100 12 squared is 144 100+144= 244 10+12= 22
