Question

(p^4+m^2 n^2)^2

Answer 1

are you supposed to square this?
start with
\[(p^4+m^2n^2)(p^4+m^2n^2)\] and then multiply out using four multiplications

Answer 2

you need help doing them?

Answer 3

yah i kept getting the wrong answer

Answer 4

ok the four are these
\[p^4\times p^4\\p^4\times m^2n^2\\p^4\times m^2n^2\\m^2n^2\times m^2n^2\]

Answer 5

first one is \(p^{4+4}=p^8\) second and third one are both \(p^4m^2n^2\) and the last one is \(m^4n^4\)

when you combine the like terms in the middle you get
\[p^8+2p^4m^2n^2+m^4n^4\]

Answer 6

hope this is more or less clear

Answer 7

thank you that is a lot of help, better than just getting the answer and not know how you got there.
