Easy exponentiation method Is there a simple way of solving, say, $x^{3/2}$?
For example, one way of solving $16^{3/2}$ is to calculate the square root of $16^3$, but I was wondering if there is a simpler mental trick for doing this that generalizes to all possible exponentiation.

One of the possible ways is to apply an exponential rule:
$$x^{\frac{3}{2}}=x\cdot\sqrt{x}$$
Example:
$$16^{\frac{3}{2}}=16\cdot\sqrt{16}=16\cdot4=64$$
