Hi guys i got some realy hard math problems here. Any help at all would be awsome. Any thoughts would allso help so no need for a whole explanation is needed. I can NOT use a calculator so if you try to solve these things you cant rely on it.

1)Define the numbers amount of digits: (10^4n²+8 ) +1)²
(Start with n=0, n=1, n=2, ...)

2)We have the number 1331. Insert 1331 amounts of zeros between the digits. Now prove that this will allways end up making a cubical number. (I think the number cvan loook like this 10330000... ...0001 or 100003030000... ...0001)

3) Prove why √2 =1 + 1/3 + 1/12 - 1/1234 is false.

4) Prove that 111...11222...22 (n amount of 1 and than n amount of 2) is not a prime number. (Prime numbers can only be divided by itself or 1. Examel of prime numbers are 2,3,5,7,11)

Shame, first time in my life i must say "I dont know how to do this" scratch

I think its shit but... dunno:

3)
√2 = 1.414...etc - ye? - yea!
So:
1/3 + 1/12=5/12
and
5/12 - 1/1234 = 6170/14808 - 12/14808 = 6158/14808 - and its fractional number < 1 while 1.414 > 1. Just by simple logic its different numbers.

a number lets say 15678 is made out of 5 digits. the digits are 1,5,6,7 and 8. and they are 5 in total. so im supposed to find a general thought of how many digits that function will give

and yes this is university math =)
