The expression you've provided is $-\log\left(p^4\right)$.

To simplify this, we'll again use the logarithm power rule, which states:

$\log(a^b) = b \cdot \log(a)$

Applying this rule to your expression:

$-\log\left(p^4\right) = - \left(4 \cdot \log(p)\right)$

This simplifies to:

$-4 \cdot \log(p)$

So, the simplified form of the expression is:

$-4\log(p)$
