Solution

Step: Multiplying the given expressions
Given, $3 x, 5 x^{2} y$ and $2 y$
Required product $= 3 x \times 5 x^{2} y \times 2 y$
$= 3 \times 5 \times 2 \times x \times x^{2} \times y \times y$
$= 15 \times 2 \times x^{3} \times y^{2}$ $[a^{m} \times a^{n} = a^{(} m + n)]$
$= 30 x^{3} y^{2}$
Hence, the answer is $30 x^{3} y^{2} .$
