Construction of number in degree is one of the simplest algebraic actions. In ordinary life the construction is applied seldom, and here on production when performing calculations – is almost universal therefore it is useful to remember how it becomes.
Instruction
1. Let's assume that we have some number and which degree is number n. Build number in degree means that it is necessary to increase number and on samoyo itself n of times.
2. Let's review several examples. To build number 2 in the second degree, it is necessary to make action: 2х2=4
3. To build number 3 in the fifth degree, it is necessary to perform operation: 3х3х3х3х3=243
4. There is a conventional designation of the second and third degree of numbers. The phrase "the second degree" is usually replaced with the word "square", and instead of a phrase "the third degree" usually tell "cube".
5. Apparently from the examples given above, duration and labor input of calculations depends on number exponent size. Squaring or a cube – quite simple task; construction of number in the fifth or big degree already demands more time and accuracies in calculations. For acceleration of this process and an exception of mistakes it is possible to use special mathematical tables or the engineering calculator.
