Question

3.(-mn^8)^2

Answer 1

what is question? Differentiate?

Answer 2

Work through the following problems on your own piece of paper or in a Word document. thats all it told me to do

Answer 3

Ohh, well what are you learning to do right now?

Answer 4

laws of exponents

Answer 5

\[\Large (-mn^8)^2\]


\[\Large (-m)^2(n^8)^2\]


\[\Large m^2n^{16}\]
So \[\Large (-mn^8)^2=m^2n^{16}\]

Answer 6

(3x^3y)^2(-4x^2y^4)^3

Answer 7

\[\Large (3x^3y)^2(-4x^2y^4)^3\]


\[\Large (3)^2(x^3)^2(y)^2(-4)^3(x^2)^3(y^4)^3\]


\[\Large 9x^6y^2(-64)x^6y^{12}\]


\[\Large (9*(-64))(x^6*x^6)(y^2*y^{12})\]


\[\Large -576x^{6+6}y^{2+12}\]


\[\Large -576x^{12}y^{14}\]


So \[\Large (3x^3y)^2(-4x^2y^4)^3 = -576x^{12}y^{14}\]
