Evaluate. \[ \begin{array}{l} (-5)^{2}= \\ (-2)^{3}= \end{array} \]

Step 1 ：The problem is asking to evaluate two expressions: (-5)^2 and (-2)^3.

Step 2 ：For (-5)^2, we need to multiply -5 by itself.

Step 3 ：For (-2)^3, we need to multiply -2 by itself three times.

Step 4 ：\((-5)^{2}= 25\)

Step 5 ：\((-2)^{3}= -8\)

Step 6 ：Final Answer: \[\begin{array}{l} (-5)^{2}= \boxed{25} \\ (-2)^{3}= \boxed{-8} \end{array}\]
