Hi

The following questions i need help on:

1)Given $\displaystyle u=\frac{x^2+t}{x^2-t}$, find t in terms of u and x.

2)Simplify $\displaystyle log\frac{4x^3}{\sqrt2}$

Note:Log is base of 2.

Someone tell me if this is correct:

$\displaystyle =3log4x-\frac{1}{2}log2$

$\displaystyle =3log4x-\frac{1}{2}$

P.S
