Instruction
1
To calculate the degree number in mathematical language means to build any number to any degree. Suppose you want the number X raised to the power n.
For this, the number X multiplied by itself n times.
2
Let X = 125, and the degree of number, i.e. n = 3. This means that the number 125 you need to multiply on itself 3 times.
125^3 = 125*125*125 = 1 953 125
Another example.
3^4 = 3*3*3*3 = 81
3
When working with a negative number you need to be careful with the signs. It should be remembered that even the degree (n) yields a plus sign, odd – minus sign.
For example
(-7)^2 = (-7)*(-7) = 49
(-7)^3 = (-7)*(-7)*(-7) = 343
4
Zero degree (n = 0) from any number will always be equal to one.
15^0 = 1
(-6)^0 = 1
(1/3)^0 = 1if n = 1, the number to multiply with itself is not necessary.
Will
7^1 = 7
329^1 = 329
5
The opposite of the construction of a number to a power is called the root.
If 5^2 = 25, the square root of 25 is 5.
If 5^3 = 125, then the root of the third degree is equal to 5.
If 8^4= 4 096, the fourth root of 4 096 will be equal to 8.
6
If n = 2, then the degree is called square if n = 3, the degree is called a cube. The calculation of square and cube of first ten numbers to produce quite easily. But with the increase in the numbererected in degree, and with increasing degree, the computations become time consuming. For such calculation we developed a special table. There are also special engineering and online calculators, software. As a simple software product for operations with degrees, you can use the table editor Excel.
