Formula of Rank Numbers
The rank numbers can be formulated as follows:
Information :
a = a number
n = the power value of a number
Example:
23 = 2 x 2 x 2
23 = 8
Basic Rule of Rank Numbers Operation
1. Multiplication Rules of The Rank Numbers Whose Principal Numbers are The Same
ap x aq = ap+q
Example:
23 x 25 = 23+5
23 x 25 = 28
23 x 25 = 256
2. Division Rules of The Rank Numbers Whose Principal Numbers are The Same
ap : aq = ap - q
Example:
38 : 35 = 38 - 5
38 : 35 = 33
38 : 35 = 27
3. Rank Rules of Rank Numbers
(ap)q = ap x q
Example:
(22)5 = 22 x 5
(22)5 = 210
(22)5 = 1024
4. Rank Rules of Two Numbers Multiplication
(a x b)p = ap x bp
Example:
(3 x 5)2 = 32 x 52
(3 x 5)2 = 9 x 25
(3 x 5)2 = 225
5. Rank Rules of Two Numbers Division
(a : b)p = ap : bp
Example:
(12 : 4)5 = 125 : 45
(12 : 4)5 = 248832 : 1024
(12 : 4)5 = 243
6. Rule of Negative Rank Number
Example:
7. Rule Rank of Fractional Number
Example:
