Find the Following Product: 1.5x(10x2y − 100xy2) - Mathematics

Find the following product:
1.5x(10x2y − 100xy2)

Solution

To find the product, we will use distributive law as follows:

$1 . 5x\left( 10 x^2 y - 100x y^2 \right)$

$= \left( 1 . 5x \times 10 x^2 y \right) - \left( 1 . 5x \times 100x y^2 \right)$

$= \left( 15 x^{1 + 2} y \right) - \left( 150 x^{1 + 1} y^2 \right)$

$= 15 x^3 y - 150 x^2 y^2$

Thus, the answer is $15 x^3 y - 150 x^2 y^2$.
