Check my answer!

OpenStudy (anonymous):

Simplify: \[a^6 \over a^2\]

OpenStudy (anonymous):

My answer: \[1 \over a^4\]

OpenStudy (anonymous):

yea seems right

OpenStudy (anonymous):

no...

OpenStudy (anonymous):

no

OpenStudy (anonymous):

without the 1 on top though

OpenStudy (anonymous):

:( ??

OpenStudy (anonymous):

yes without the one on the top

OpenStudy (anonymous):

Okay... At least it was my second guess :P

OpenStudy (anonymous):

it should be \[a ^{4}\]

OpenStudy (anonymous):

it would be \[a^{4}\]

OpenStudy (anonymous):

\[\frac{ a^6 }{ a^2 }=\frac{ a\cdot a\cdot a \cdot a \cdot a \cdot a }{ a \cdot a }=\frac{ \cancel{a}\cdot \cancel{a}\cdot a \cdot a \cdot a \cdot a }{ \cancel{a}\cdot \cancel{a}}=a^4 \]

OpenStudy (anonymous):

there is a rule for exponents... \[\frac{ x^n }{ x^m }=x^{n-m}\]

OpenStudy (anonymous):

@BlossomCake, does this make sense?

OpenStudy (anonymous):

Yes, it does! Thanks so much! :D
