Алгебра: вираз (x-1)(x^2+x+1)+(3-x)(9+3x+x^2)(a+1)(a-1)(a2-a+1)(a^2 +a+1)(a^6+1)(a^12+1)(a^24+1)

Masha3334 · Answer

(x³-1)+(27-x³)(a³-1)(a³+1)(a^6+1)(a^12+1)(a^24+1)=
=(x³-1)+(27-x^3)(a^6-1)(a^6+1)(a^12+1)(a^24+1)=
=(x³-1)+(27-x^3)(a^12-1)(a^12+1)(a^24+1)=
=(x³-1)+(27-x^3)(a^24-1)(a^24+1)=
=(x³-1)+(27-x^3)(a^48-1)
