Restate each in exponential form:

1)$\displaystyle log_aa^3$

My work:

$\displaystyle a = a^3$

--

2)$\displaystyle log_bb^ \frac {3}{2}$

My work:

$\displaystyle b = b^ \frac {3}{2}$

--

3)$\displaystyle log_kk^{\sqrt3} $

My work:

$\displaystyle k = k^{\sqrt3}$

--

4)$\displaystyle log_22^{x} $

My work:

$\displaystyle 2 = 2^{x}$

Can someone check my work, and if it's wrong can you please tell me how to correct it?
