To simplify the expression \( p^{-5} \times p^{3} \), you can use the property of exponents that states when multiplying terms with the same base, you add their exponents. This is expressed mathematically as follows:

\[

p^a \times p^b = p^{a + b}

\]

In this case, the exponents are -5 and 3. Therefore, you add these exponents together:

\[

-5 + 3 = -2

\]

This results in:

\[

p^{-2}

\]

The expression \( p^{-2} \) signifies that the exponent is negative, which implies that the term can also be rewritten as \( \frac{1}{p^2} \) if needed. However, since the question only asks for the simplified form, \( p^{-2} \) is already in its simplest exponent format.

This makes \( p^{-2} \) the correct outcome for the simplification of the initial expression \( p^{-5} \times p^{3} \).
