Answer: 400 is a perfect square of 20 but not a perfect cube. Grouping the prime factors of 1000 into triples, we are not left over with any factor. This means three multiplied by itself three times. When you multiply a whole number (not a fraction) by itself, and then by itself again the result is a cube number. Another cube number is 27 because it’s 33 (3 x 3 x 3, or “three cubed”).
For example, 8 is a cube number because it’s 2 x 2 x 2 (2 multiplied by itself twice) this is also written as 23 (“two cubed”). Why is 8 a cube number?Ī cube number is the result when a number has been multiplied by itself twice. The first five cube numbers are: 1, 8, 27, 64 and 125. Is 8 a cube number?Ī cube number is the answer when an integer is multiplied by itself, then multiplied by itself again. For example, 8 is a perfect cube because 3√8 = 2. Is 8 a perfect cube?Ī perfect cube is a number which is equal to the number, multiplied by itself, three times. Using exponents is a short way of saying “multiply the number by itself.” The little number up above tells you how many times to multiply the number by itself. When used in the context “Fn,” it refers to a function evaluated for the value “n.” The text n-1 and n-2 are also subscripts that define previous values of “n” in the sequence. Subscripts have many scientific applications, including mathematics, computer science, and chemistry. What is the little number below the big number? In that case we use subscripts: P 1 P_ P2, P 3 P_3 P3 and so on. For example, P stands for pressure and in some equations you’ll have more than one pressure represented. Subscripts are those little numbers in the bottom right Well, the variables in science often represent something specific. You can achieve this by navigating to the insert tab, then equation and lastly script where you will find a formatted box with the superscript and subscript vertically aligned.
