Question

Simplify: i) (6x+5y)³​

Answer 1

Answer:

216x^3+125y^3+540x^2y+540xy^2

Step-by-step explanation:

(a+b)^3 = (a+b)^2(a+b)

by solving this you'll get

a^3+b^3+3a^2b+3ab^2

(by putting the value of a=6x & b=5y)

you'll get

(6x)^3+(5y)^3+3(6x)^2(5y)+3(6x)(5y)^2=

216x^3+125y^3+540x^2y+540xy^2 (Ans)

Answer 2

(6x+5y)*3

6x*3+5y*3

216x*3+125y*3
