@rags-at-work unit digit of 1^5 , 11^5 ,21^5 ....91^5 will be same  so 10(1^5)

same is true for 3^5 ,13^5 ...93^5  sum will be 10(3^5)

similarly for 5, 7 and 9

 in the end summation will look like 10[1^5 + 3^5 .....9^5] 


Guys the registration handbook says signature should be of 1000mm.

Can any anyone shed light on this please.

I don't think we can have a signature that large ?
