lol og copi me

OG nuu i said pie

OpenStudy (s4sensitiveandshy):

\[(x^a)^b= x^{a \cdot b}\]\[x^m +x^n\] when multiply same base, add exponents

rebeccaxhawaii (rebeccaxhawaii):

okayso remember \[(x^a)^b=x^{a*b}\]

rebeccaxhawaii (rebeccaxhawaii):

dang it they beat me to it ;p

OpenStudy (s4sensitiveandshy):

the exponent represents how many times we should multiply the base by itself \[x^1 * x^1 * x^1=x^3\] for your question first multiply the inner and outer exponents and then add them p.

rebeccaxhawaii (rebeccaxhawaii):

OG then add the exponents

\[(n ^3)^3 · (n ^4)^5\] \[(n ^3)^3 = n^9\] \[(n ^4)^5 = n^{20}\] \[n^9 + n ^{20} = n ^{29}\] @AloneS

Thanks Kendric<3

OpenStudy (kendricklamar2014):

Your welcome. Glad I could help :)

OpenStudy (zarkon):

you should not write \(n^9 + n ^{20} = n ^{29}\) since this is not true. write... \[n^9 \times n ^{20} =n^{9+20}= n ^{29}\]

OpenStudy (kendricklamar2014):

True, my mistake. Thanks @Zarkon
