Study Notes
- A power is a shortened way of writing a multiplication where a factor is repeated multiple times. The base is the number being repeated (e.g., 7 or 9) and the exponent indicates how many times the base is repeated.
- Powers are written with the base number at the bottom and the exponent (indicating repetition) written as a small number on top.
- Special names are given to powers with exponents of 2 and 3: "to the square" for 2 and "to the cube" for 3. For example, 5 squared is read as 5 to the power of 2.
- Understanding the product of powers involves correctly multiplying the base number by itself the number of times indicated by the exponent. For instance, 2 cubed means multiplying 2 by itself three times.
- Notably, any number raised to the power of 1 will always equal that number. For example, 10 to the power of 1 equals 10, and 1 to the power of any number equals 1.
Learn about powers in mathematics where a base number is raised to an exponent indicating how many times it is repeated. Discover special names for exponents of 2 and 3, and how any number raised to the power of 1 equals that number.
