How do you factor and simplify these algebraic expressions step by step? Please help!:
\[(x+9)^{1/4}+(x+9)^{3/4}\]
and
\[(x+7)^{-1/5}+(x+7)^{-6/5}\]
would it help if you imagine \[(x + 9)^{1/4} + (x+ 9)^{3/4}\]t be like \[(x+9) + (x+ 9)^3\] since they have common denominators you can imagine it like this then just put the necessary changes later. do you know how to factor it out?
Honestly, from there, no, i'm not sure
not even \[(x+ 9) + (x+ 9)^3\]?? what about \[a + a^3\] do you know gow to factor that out?
how*
Over the summer I have blanked on everything math.
you factor out \[a+ a^3\]as \[a(1 + a^2)\] so now...do you know how to do \[(x+ 9) + (x+9)^3\]
\[1+(x+9)^{3}\]
?
no. \[(x+9)[ 1 + (x+9)^2]\]
there should be x + 9 outside
now just put/4 on all the exponents of x + 9 and you're done
i have to go now so i hope you got it. good luck
