Base is the number used a factor. The exponent tells how many times a base is used as a factor. Numbers like 100 are perfect squares because they are the squares of whole numbers. A prime number has factors of only 1 and itself. Composite numbers have more than just 2 factors. When finding the prime factorization, you must always make a factor tree. The two form to express the prime factorization of a number are expanded and exponential. The only prime even number is? 4 12 2 How are Zero and one classified? Prime Neither composite Express each power as a product of the same factor. 10 to the fourth power 10 x 10 x 10 x 10 6 x 6 x 6 x 6 x 6 x 6 6 to the sixth power Elena has a fish tank that holds 25gallons of water.
