# Simplify an expression.

Don't know how to do this.

Simplify the expression, show steps:

$$\large \dfrac {a^{-\frac 14}a^{\frac 32}}{a^{\frac 13}}$$ Write the answer using only positive exponents. Assume that all variables are positive real numbers.

Google "negative fraction powers" and see where it will take you... –  JMCF125 Nov 22 '13 at 17:04

$$a^{-b} = \frac 1{a^b}$$
$$a^b\cdot a^c = a^{b + c}$$
$$\dfrac{a^b}{a^c} = a^{b - c}$$
