**Four squared in math is 16, as any number squared is multiplied by itself.** Another way to express four squared is to say four to the second power.

A number to the third power is cubed, so four cubed is 64. The exponent is written as a superscript to the number to which it applies. Exponents are used frequently in algebra.

Multiplying exponents with the same base number requires adding the exponents and keeping the base. For example, four squared times four cubed equals four to the fifth power (two plus three), or 1,024. A number to the first power is simply the number.
