1. $\displaystyle ^3\sqrt{x}=4$

2. $\displaystyle 2x^2-17=-8$

3.$\displaystyle -7*2^x=-224$

4. $\displaystyle (\frac{2}{3})^x=\frac{3}{2}$

5. $\displaystyle 3^x=\frac{1}{9}$

I've picked out these problems in relation to one question. What do I do with all these indexes and powers? I totally forgot.

Thanks.
