Answer
$\text{Leading Term: }
8p^4
\\\text{Leading Coefficient: }
8$
Work Step by Step
In descending powers of the variables, the given expression, $
-p^2+5+8p^4-7p
,$ is equivalent to
\begin{array}{l}\require{cancel}
8p^4-p^2-7p+5
.\end{array}
The expression above has the following characteristics:
\begin{array}{l}\require{cancel}
\text{Leading Term: }
8p^4
\\\text{Leading Coefficient: }
8
.\end{array}
