A)(2a-b)^6 = (2a-(a^3 b^3))^6 = (2a-a^3 b^3)^6 = (a(2-b^3))^6 = a^6 (2-b^3)^6Коэффициент при x=a^3 b^3 равен (2-b^3)^6
B)(2a-3b)^7 = (2a-(a^2 b^5))^7 = (2a-a^2 b^5)^7 = (a(2-b^5))^7 = a^7 (2-b^5)^7Коэффициент при x=a^2 b^5 равен (2-b^5)^7
A)
(2a-b)^6 = (2a-(a^3 b^3))^6 = (2a-a^3 b^3)^6 = (a(2-b^3))^6 = a^6 (2-b^3)^6
Коэффициент при x=a^3 b^3 равен (2-b^3)^6
B)
(2a-3b)^7 = (2a-(a^2 b^5))^7 = (2a-a^2 b^5)^7 = (a(2-b^5))^7 = a^7 (2-b^5)^7
Коэффициент при x=a^2 b^5 равен (2-b^5)^7
