Evaluate: $$(256)^{0.16}\, \times\, (256)^{0.09}$$

The value of $$\displaystyle \frac {1}{(216)^{-2/3}}\, +\, \displaystyle \frac {1}{(256)^{-3/4}}\, +\, \displaystyle \frac {1}{(32)^{-1/5}}$$ is:

The value of $$(8^{-25}\, -\, 8^{-26})$$ is

Evaluate: $$(0.04)^{-1.5} $$

$$\displaystyle 2^{73}-2^{72}-2^{71}$$ is the same as :

if $$\dfrac{(23)^{9}-(23)^{8}}{22}=(23)^{x}$$ then $$x$$ equals : 

Simplify : $$\displaystyle \frac{2^{2009}-2^{2007}}{2^{2006}-2^{2008}}$$

The value of $$5^{1/4}\, \times\, (125)^{0.25}$$ is

Simplify: $$\displaystyle \frac{3^{-5} \times 10^{-5} \times 125}{5^{-7} \times 6^{-5}}$$

$$\displaystyle \left ( \frac{-4}{5} \right )^{4} \times \left ( \frac{-4}{5} \right )^{2} = \frac{16}{25}$$
