The power of a power rule is an important exponent rule (law of exponent) used to simplify an expression of the form $(x^{m})^{n}$, where the base x is raised to a power m and the entire expression $x^{m}$ is raised to the power n again.
Laws of Exponents. Exponents are also called Powers or Indices. The exponent of a number says how many times to use the number in a multiplication. In this example: 82 = 8 × 8 = 64. In words: 8 2 could be called "8 to the second power", "8 to the power 2" or simply "8 squared". Try it yourself:
Exponents. The exponent of a number says how many times to use the number in a multiplication. In 82 the "2" says to use 8 twice in a multiplication, so 82 = 8 × 8 = 64. In words: 8 2 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared".
It is often described as "4 to the power of 3". So the exponent is also sometimes called "the power of" number. Before we move on, let's do one more simple exponent example:
The power (or exponent) of a number says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number. In this example the little "2" says to use 8 two times in a multiplication: 8 2 = 8 × 8 = 64.
What are powers? Using. powers. is a shorthand way of writing repeated multiplication using the same number. For example, rather than writing 4 x 4 x 4 it can be simplified to 4³. This...
21 Νοε 2023 · Powers in math are the exponents that show how many times a base will be multiplied by itself. In 9^2, the 2 is the power or exponent. 9^2 = 9 x 9 = 81
