Power of two - Wikipedia
网页A power of two is a number of the form 2 n where n is an integer, that is, the result of exponentiation with number two as the base and integer n as the exponent. Powers of two with non-negative exponents are integers: 2 0 = 1, 2 1 = 2, and 2 n is two multiplied by itself n times. [1] [2] The first ten powers of 2 for non-negative values of n are:
Exponents - Math is Fun
网页The exponent of a number says how many times to use the number in a multiplication. In words: 8 2 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared". Exponents make it easier to write and use many multiplications. Example: 96 is easier to write and read than 9 × 9 × 9 × 9 × 9 × 9.
2.1 Use the Language of Algebra - Prealgebra 2e - OpenStax
网页To simplify a numerical expression means to do all the math possible. For example, to simplify 4 · 2 + 1 4 · 2 + 1 we’d first multiply 4 · 2 4 · 2 to get 8 8 and then add the 1 1 to get 9. 9. A good habit to develop is to work down the page, writing each step of the process below the previous step. The example just described would look ...
