What is the nth root of 244?

Answer 1

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.

Answer 2

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.
