(3)^-5= (6)^-2= (4)^-3= (5)^-2=

Vamos calcular cada uma das expressões dadas:

1. $(3)^{-5}$:
$$(3)^{-5} = \frac{1}{(3)^5} = \frac{1}{3^5} = \frac{1}{243}$$

2. $(6)^{-2}$:
$$(6)^{-2} = \frac{1}{(6)^2} = \frac{1}{6^2} = \frac{1}{36}$$

3. $(4)^{-3}$:
$$(4)^{-3} = \frac{1}{(4)^3} = \frac{1}{4^3} = \frac{1}{64}$$

4. $(5)^{-2}$:
$$(5)^{-2} = \frac{1}{(5)^2} = \frac{1}{5^2} = \frac{1}{25}$$

Portanto, as respostas são:

$$\begin{array}{l} (3)^{-5} = \frac{1}{243} \\ (6)^{-2} = \frac{1}{36} \\ (4)^{-3} = \frac{1}{64} \\ (5)^{-2} = \frac{1}{25} \end{array}$$
