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.

∙ 8y agoThat 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.

Can zero be used as a radical?
yes the nth root of zero is always zero
If a is a positive real number and n is even how many roots are there?
Assuming that you mean the nth. root: two - a negative and a positive root.
A to the 1 divided by n power?
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.
What are the two numbers that equal 22 and the square root of the two numbers equal 244?
10 squared is 100 12 squared is 144 100+144= 244 10+12= 22
To convert an nth root notation to one that uses fractional exponents you change the index n to the exponent?
1/n
How do we stop the nth root?
The nth root is unstoppable. You must sit back and wait. Hopefully you will survive it as it takes its deadly course.
What is the square root 244 rounded to the nearest hundredth?
244.00
How do you find the nth root of a number?
You seem to be unaware of the fact that you can obtain the answer easily by using the scientific calculator that comes as part of your computer. In general the nth root is extremely difficult to find.
What are forms of radical?
The radical symbol, otherwise known as the "square root sign", lets you take the nth root of any number.Any number can be placed above, and slightly to the left, of the square root sign, to indicate the nth root. For example, the cube root of 27 is 3.The number inside the square root sign (that which you are finding the square root of), is called the radicand.
Can zero be used as a radical?
yes the nth root of zero is always zero
If a is a positive real number and n is even how many roots are there?
Assuming that you mean the nth. root: two - a negative and a positive root.
What is the square root of the number 244?
The square roots are approx -16.6 and +16.6
Proof of Nth root is irrational?
You can't prove this proposition because it isn't true.Proof: the fifth root of 1024 is 4, and 4 is not irrational.It is true that, when N is an integer greater than 1, the Nth root of any integer greater than 1 is either an integer orirrational, but that's a different matter.
How is geometric mean computed?
The geometric mean is the nth root of the product of the numbers. So this means (pun intended) multiply the numbers together and then take their nth root. Let's look at 2, 4, and 8 . Their product is 64 and the cube ( 3rd) root of 64 is 4. Of course, most of the time, the answer will not be rational.
Does the nth root of x2 always exist?
The nth root of x2 can be expressed as: x2/n Thinking of it that way, we can see that no, it can't always exist - but almost always. The only condition in which it can't exist is when n = 0, as that would give us division by zero.
Are there any real roots in negative sixty?
What does this question mean? -60 has a real cube root, a real fifth root. In fact a real nth root for all odd n.
Of all the numbers what number that is perfect?
only the number 1 (one)because it is perfect nth root .
