Magical properties
of cube numbers.
There are
many hidden properties among cube numbers.Few are described below.
Different
ways of expressing n3
43
= 42 x 4 + 4x02 =
16 x 4 +0
= [42
- 1x4](4+1) + 4 x 12 = 12 x 5 + 4 x 1
=[ 42- 2x4](4+2) + 4 x 22 = 8 x 6 + 4 x 4
= [42-
3 x4](4+3) + 4 x 32 = 4 x 7 +
4 x 9
For 53
53
= 25 x 5 + 0
= 20 x 6 + 5 x 1
= 15 x 7 + 5
x 4
= 10 x 8 + 5
x 9
= 5 x 9 + 5
x 16
13
= 1
23
= 1 +(1+6)= 1+7 = 8
33=
1 +(1+6) +(1+6+12)= 1+7+19= 27
43
= 1+(1+6)+(1+6+12)+(1+6+12+18)= 1+7+19+37 =64
53=
1+(1+6)+(1+6+12)+(1+6+12+18)+(1+6+12+18+24)= 1+7+19+37+61= 125
13
= 02(6) +1
23
= 12(6)+2
33=
22(6) +3
43
= (12 +32) 6 + 4
53
= (22 + 42 ) 6 + 5
63
= (12 +32 +52) 6 +6
73
= (22+42+62) 6 + 7
83
= (12+32+52+72) 6 +8
93
= (22+42+62+ 82 )6 +9
103
= (12 +32 +52 +72 + 92)
6 + 10
In
general a3 = [ 12 +32
+ 52 + ……. (a-l)2] 6 + a if a is even
= [ 22 + 42
+ 62 + (a-1)2] 6
+ a if a is odd
