B. (-5)(-7)

C. ${(-3)}^3$

D. $0\times (-5)$

To select: The given expression that evaluate to negative value.

Answer to Problem 1STP

  ${\left(-3\right)}^3$

Explanation of Solution

Given information:

The given expressions are

  $\begin{array}{l}\left(A\right){\left(-2\right)}^2\\ \left(B\right)\left(-5\right)\left(-7\right)\\ \left(C\right){\left(-3\right)}^3\\ \left(D\right)0\times \left(-5\right)\end{array}$

Calculation:

Solve the above expressions,

  $\begin{array}{l}\left(A\right){\left(-2\right)}^2=4\\ \left(B\right)\left(-5\right)\left(-7\right)=35\\ \left(C\right){\left(-3\right)}^3=-27\\ \left(D\right)0\times \left(-5\right)=0\end{array}$

Since, expression C has negative value.
