Question

Really dumb question

Answer 1

\[(u^4)(1-2u^2+u^4) \neq u^4-2u^8+u^16\]

Answer 2

? When multiplying, dont you multiply the exponents? not add?

Answer 3

\[(u^a)^b = u ^{a*b}\]

I guess I see the difference, I just need someone to confirm

Answer 4

you add them

Answer 5

\[u^{a}*u^{b} = u^{a+b}\]

Answer 6

thank ya!
