How to Use Squared in Excel
Microsoft Excel offers a wide variety of formulas for use in nearly any situation, including the ability to raise a number to an exponential power. This feature is used when raising any real number to any power, including positive and negative exponents and common exponents such as squared or cubed.
Launch Microsoft Excel, then enter the number to be squared into cell A1. Press "Enter" to move the focus to cell A2.
Press the Equal sign "=" and type the word "Power" followed by a left parenthesis "(" and then click once on cell A1 to select it as the source. Type a comma "," and then the number "2" and a right parenthesis ")" and press "Enter." The cell A2 now shows the squared value of whatever is entered into cell A1, or in other words the contents of cell A1 raised to the second power. The final formula will look like this: =POWER(A1,2)
Change the number in cell A1 to any other number and the formula in cell A2 will automatically update to reflect the value of cell A1 raised to the second power.
Tips & Warnings
- Save a copy of the spreadsheet as a backup before making changes to formulas or the contents.
- Change the number after the comma inside the parenthesis in cell A2 to change the power to a different number. For example, =POWER(A1,3) is the value of the number in A1 "cubed," or raised to the third power.
- Formulas can be easily overwritten by users who are unaware that a formula is calculating a field. Enable protection on cells that contain formulas to prevent accidental erasure of the formula with data.
