Ответ:
27x^6*y^12; -15a^5*b^3; 7; x^2-6y+5+x^3; 4 (a^2*b + b^2 - 145).
Объяснение:
1) (3x^2*y^4)^3 = 27x^6*y^12.
2) 5ab^2 * (-3a^4*b) = -15a^5*b^3.
3) x^2-3y+6+(-x^2+3y+1) = x^2-3y+6-x^2+3y+1 = 7.
4) x^2-3y+6-(-x^3+3y+1) = x^2-3y+6+x^3-3y-1 = x^2-6y+5+x^3.
5) 8a^2b + (-5a^2b + 4b^2 + (a^2*b - 582 + 2 )) = 8a^2*b+(-5a^2*b + 4b^2 + a^2*b - 582 +2) = 8a^2*b - 5a^2*b + 4b^2 + a^2*b - 582 + 2 = 4a^2*b + 4b^2 - 580 = 4 (a^2*b + b^2 - 145).
