i want to know if i did it right..thanks

Answer 1

i get (m^2-6n^2)(m^4+6n^2m^2+36n^4)

Answer 2

you are correct

Answer 3

That looks correct to me lordofpens. :)

Answer 4

This is a difference of cubes,

Answer 5

\[m^6 -216n^6 = (m^2)^3-(6n^2)^3\]\[a^3-b^3 = (a-b)(a^2+ab+b^2)\]

Answer 8

i get (11a-3b63+5x)(11a+3b^3-5x)
