Answer 1

Răspuns:

Explicație pas cu pas:

a)

1^3 + 2^3 + 3^3 + 4^3 = 1 + 8 + 27 + 64 = 100

b)

10^2009 = 100*10^2007 = 100*(10^669)^3

= (1^3 + 2^3 + 3^3 + 4^3)*(10^669)^3

= 1^3*(10^669)^3 + 2^3*(10^669)^3 + 3^3*(10^669)^3 + 4^3*(10^669)^3

= (10^669)^3 + (2*10^669)^3 + (3*10^669)^3 + (4*10^669)^3

a = 10^669

b = 2*10^669

c = 3*10^669

d = 4*10^669
