Answer 2

Q..(3a+2b)^3-(3a-2b)^3

Let 3a be x and 2b be y

Then

(x+y)^3-(x-y)^3

=x^3+y^3+3×xy(x+y)-{x^3-y^3-3×xy(x-y)}

=x^3+y^3+3x^2y+3xy^2-{x^3-y^3-3x^2y+3xy^2}

=x^3+y^3+3x^2y+3xy^2-x^3+y^3+3x^2y-3xy^2

=y^3+y^3+3x^2y+3x^2y

=2y^3+6x^2y

Put the value of x and y

=2×(2b)^3+6×(3a)^2×2b

=2×8b^3+6×9a^2×2b

=16b^3+108a^2b

Ok
