x^3+5=x^8 t^3 * t^3 = t^6 i guess it's u^6 g^2+4g+4 not sure abt (z-3)^3 expanding (z-3)^3 could it be: (z-3).(z+3)^2 ?? =>(z-3) (z^2+3z+9)

not sure abt (z-3)^3
expanding (z-3)^3
could it be:
(z-3).(z+3)^2 ??
=>(z-3) (z^2+3z+9)
- RiderOfGiraffes 16y agoOK, in the first one you need brackets : x^3+5 is not usually understood to be the same as x^(3+5), but the answer is right, and the process is right. The others are right too. So (g+2)^2 is equal to g^2+4g+4, but it's also equal to (g+2).(g+2) [where I've used the dot for multiplication] Does that help you for (z-3)^3 ??
