Question

(2a+3b) (2a+3b) (2a+3b)
​

Answer 1

Ответ:

$8a^3 + 27b^3 + 36a^2b + 54b^2a$

Объяснение:

$(2a+3b)(2a+3b)(2a+3b) = (2a+3b)^3 = (2a)^3 + (3b)^3 + 3((2a)^23b) + 3((3b)^22a) = 8a^3 + 27b^3 + 36a^2b + 54b^2a$

Answer 2

(2a+3b)×(2a+3b)×(2a+3b)

(4a²+6ab+6ab+9b²)×(2a+3b)

(4a²+12ab+9b²)×(2a+3b)

8a³+12a²b+24a²b+36ab²+18ab²+27b³

8a³+36a²b+54ab²+27b³
