Question

Evaluate the expression when $x=-5$ and $y=-7$.

$2x^{2}y$

Short answer

The value of given expression would be $-350$.

Step-by-step solution

Step 1. Given Information.

An expression: $2x^{2}y$

Step 2. Calculation.

To find the value of the given expression, we will substitute $x=-5$ and $y=-7$ in our given expression as shown below:

$\begin{array}{c}2x^{2}y=2{\left(-5\right)}^2\left(-7\right)\left(\text{Substitutinggivenvalues}\right)\\ =-14\cdot 25\left(\text{Usingproperty}\left(-\right)\left(-\right)=\left(+\right)\right)\\ =-350\end{array}$

Step 3. Conclusion.

The value of given expression would be $-350$.
