The correct answer is $$z^{\frac{4}{25}}$$.

To find t in terms of z, first we need to find the value of t in terms of p:
$$t^{\frac{1}{2}} = p^{\frac{-2}{3}} → (t^{\frac{1}{2}})^2= (p^{\frac{-2}{3}})^2 → t = p^{\frac{4}{9}}$$
Now, solve for p
$$p^{\frac{1}{2}} = z^{\frac{-3}{5}} →(p^{\frac{1}{2}} )^2 = (z^{\frac{-3}{5}})^2 → p =z^{\frac{9}{25}}→$$
$$p^{\frac{4}{9}} = z^{\frac{4}{25}} →$$
$$t = p^{\frac{4}{9}}$$ and $$(p)^{\frac{4}{9}} = z^{\frac{4}{25}}$$, therefore, $$t =z^{\frac{4}{25}}$$

### What people say about "Number Properties Puzzle - Challenge 19"?

1. There are typos (not p^1/6) and the solution is incorrect anyway. p^ (-2/3) ^ 2 is not -4/9. You add powers, you don’t multiply them.
