X2 A number to the second power is squared.
The "second power" means squared. "Squared" means multiplied by itself. Thus M to the second power = M times M.
squared is simply written as a constant raised to the second power. For example, 3 to the second power=9. The way to write the power, or exponent, is by writing a superscript (small number in the uppper righthand corner of the number or variable) number 2.
4 cubed is 64, 3 squared is 9, so 55.
7 raised to the second power is the same way as saying "seven squared". Seven squared is equal to 49.
