Question

Calculati 5 la a 2+(2011la 0+0 la 2+2011la 1):2011

Answer 1

$5^{2} +(2011^0+0^2+2011^1):2011=25+(1+0+2011):2011= \\ \\ =25+2012:2011=25+ \frac{2012}{2011} = \frac{50275+2012}{2011} = \\ \\ = \frac{52287}{2011}$

Answer 2

5² + (2011⁰ + 0² + 2011¹) : 2011 = 

= 25 + (1 + 0 + 2011) : 2011

= 25 + 2012 : 2011

= 25 + 2012/2011

= (50275 + 2012)/2011

= 52287/2011
