Find product:
$(2.3 x y) \times(0.1 x) \times(0.16)$

Answer
To multiply algebraic expressions, we can use commutative and associative laws along with the law of indices, $a^m \times a^n=a^{m+n}$.
We have:
$(2.3 x y) \times(0.1 x) \times(0.16)$
$=(2.3 \times 0.1 \times 0.16) \times(x \times x) \times y$
$=(2.3 \times 0.1 \times 0.16) \times\left(x^{1+1}\right) \times y$
$=0.0368 x^2 y$
Thus, the answer is $0.0368 x^2 y$.
