Simplifying rational expression
(a^4)(³√a(a^5))
Hopefully that makes sense.

e^(i*pi)

Do you mean $a^4 \cdot \sqrt[3]{a(a^5)}$ or $a^4 \cdot \sqrt[3]{a} \cdot a^5$

You would do well to recall the exponent laws, namely the one that says $m^n \cdot m^p = m^{n+p}$ and the one that says $\sqrt[n]{m} = m^{1/n}$

Re: Simplifying rational expression
I actually figured it out on my own. I meant the first one anyway.

Re: Simplifying rational expression
May I ask why you titled this "Simplifying rational expression" when there is no rational expression involved?
