Calculati a=2011 la puterea a 3-2011 la puterea a 2*2010-(2011*2010 la puterea a doua - 2010 la puterea a 3

Răspuns :

a = 2011^3 - 2011^2×2010 -(2011×2010^2-2010^3)

a = 2011^2 × (2011 - 2010) - 2010^2×(2011 - 2010)

a = 2011^2 × 1 - 2010^2 × 1

a = 2011^2 - 2010^2

a = 4 044 121 - 4 040 100

a = 4 021
