Given that n⁵ = 133⁵ + 110⁵ + 84⁵ + 27⁵.
Find that value of n using only pen and paper.

(In reply to re: Assuming... by Ady TZIDON)

1.  So the assumption n is an integer was correct.

No need to "assume"- the sum of integers is always an integer.

All that was known for certain was n^5 is an integer.  There's no guarantee in the equation that n is.

2. 133*(4)^1/5 < 4^1.5 < 200 is not clear how you get 200

This was a typo.  I realized 4^(1/5) is a little under 1.5 and 133*1.5 = 199.5

It should read

133*4^(1/5) < 133*1.5 < 200
