Question
Find the product:
$4.1 x y(1.1 x-y)$
$4.1 x y(1.1 x-y)$
✓
Answer
To find the product, we will use distributive law as follows:
$4.1 x y(1.1 x-y)$
$=(4.1 x y \times 1.1 x)-(4.1 x y \times y)$
$=[(4.1 \times 1.1) \times x y \times x]-(4.1 x y \times y)$
$=\left(4.51 x^{1+1} y\right)-\left(4.1 x y^{1+1}\right)$
$=4.51 x^2 y-4.1 x y^2$
Thus, the answer is $4.51 x^2 y-4.1 x y^2$
$4.1 x y(1.1 x-y)$
$=(4.1 x y \times 1.1 x)-(4.1 x y \times y)$
$=[(4.1 \times 1.1) \times x y \times x]-(4.1 x y \times y)$
$=\left(4.51 x^{1+1} y\right)-\left(4.1 x y^{1+1}\right)$
$=4.51 x^2 y-4.1 x y^2$
Thus, the answer is $4.51 x^2 y-4.1 x y^2$
