Question
Find the product:
$250.5\text{xy}\big(\text{xz}+\frac{\text{y}}{10}\big)$
✓

Answer

To find the product, we will use distributive law as follows:$250.5\text{xy}\big(\text{xz}+\frac{\text{y}}{10}\big)$
$=250.5\text{xy}×\text{xz}+250.5\text{xy}×\frac{\text{y}}{10}​​​​​​​$
$=250.5\text{x}^{1+1}\text{yz}+25.05\text{xy}^{1+1}$
$=250.5\text{x}^2\text{yz}+25.05\text{xy}^2$
Thus, the answer is $250.5\text{x}^2\text{yz}+25.05\text{xy}^2$
