How to Type Squared on PowerPoint
The squared symbol in math is a type of exponent. An exponent is the number of times that a number is multiplied by itself. The term "squared" refers to a number to the power of two, or multiplied by itself once. The squared symbol appears as a superscript, smaller text positioned above the baseline of the line of text.
Type a "2" after the number you want to square. Select the "2" with the cursor.
Go to the "Home" tab in the ribbon, and click the expansion arrow in the lower-right corner of the "Font" menu.
Place a check in the "Superscript" box. Leave the "Offset" box at the default setting. Click "OK" to apply the settings to the presentation.
