Question

can (5n^3)^2 + 2n^2(n^3+4n^4) be simplified further than 25n^6 + 2n^2(n^3+4n^4). All of my answer checks say no. Just verifying my answer. Thank you!

Answer 1

i would be
25n^6 + 2n^5*(1+4n)

Answer 2

i think u need to expand it
for (5n^3)^2 = 25n^6 and expand of
2n^2(n^3+4n^4) = 2n^5 + 8n^6
just add of them be:
25n^6 + 2n^5 + 8n^6
= 33n^6 + 2n^5

Answer 3

ed, your answer checks out but I have zero idea how you arrived to the conclusion. RadEn, Thank you! That completely makes sense to add the like terms in the end.
