Fun Maths

If you multiply any three digit number by 11 and then again multiply the product with 91 then see the result.

For example

Let us take a 3 digit number 578

now 578 x 11 = 6358

then 6358 x 91 = 578578

see the number 578  repeats in the result

Another example 741

741 x 11 = 8151

8151 x 91 = 741741

Special Cube Roots

Check the number 4913

The sum of its digits is 4 + 9 + 1+ 3 = 17
The cube root of 4913 = 17

case 2 : 5832

The sum of its digits is 5 + 8 + 3+ 2 = 18

The cube root of 5832 = 18

case 3 : 19683

Sum of digits 1 + 9 + 6 + 8 + 3 = 27

The cube root of 19683 = 27
