 # Excel POWER function

In this article, we will learn how to use the POWER function in Excel.

In mathematics power operator, gets the power of a number.

33= 3 * 3 *3 = 27
3 raised to the power 3, says 3 multiplied by its own number three-time is equal to 27.

271/3= 33*(1/3)= 3
27 raised to the power (?), says which number gets multiplied 3 times to get 27, 3 is the answer. This is called finding the root of a number.

POWER function calculates the power of a number.

Syntax:

=POWER ( number, power)

For example: IF you wish to get the power of 4 raised to 3
Write the formula in the cell =POWER(4,3) Let’s learn this through an example shown below.
Here we have numbers in one column and power of the numbers in the second column. Use the formula to get the POWER

=POWER(A2,B2) Press Enter and copy the formula in other cells using Ctrl + D shortcut. As you can see the formula returns #NUM error when we calculate the root of a negative number.

Hope you learned how to get the power or root of a number using POWER function in Excel. Explore more articles here on Excel Mathematical functions here. Please feel free to state your query or feedback in the comment section below. We will help you.

# How to use the SQRT Function in Excel

In this article, we will find out how to calculate the square root  of a number using the SQRT function in excel.
SQRT function is used when we need to find the square root of a number in Excel.

The square root of x is referred to as x.

The Root of a number is inverse of Power of the number.

Square of a number = Power(2) of a number

The square root of a number = power(½) of a number

 y = x2   (y)1/2 = x

Syntax of SQRT:

=SQRT(number)

Number : input number you want the square root of.
Let’s look at the example shown here
Use the formula to get the square root of the number in cell B3.

=SQRT(B3)

B3 : input number as a cell reference. Press Enter to see the square root of 25. The square root of 25 is 5.

You can customize your formula with these basic functions. As you can see by using the mathematical function in Excel you can perform many exponents function. Please do find more articles on the mathematical formulation here.

Notes:

1. The function returns the #VALUE! Error, if the argument to the function is non numeric.
2. The function returns the #NUM! Error, if the argument to the function is less than zero. Use the ABS function to the input number to get the square root of a positive number.

Hope you understood how to use SQRT function and referring cell in Excel. Explore more articles on Excel mathematical and trigonometric functions here. Please feel free to state your query or feedback for the above article.
