Mathematics

$\frac{5}{4k^{2}}$

Step-by-step explanation:

We have the following expression and we need to simplify it using the rules of multiplication of fractions and multiplication and division of exponents with the same base:

$(\frac{5k}{6})(\frac{3}{2k^{3}})=\frac{15 k}{12 k^{3}}$

Simplifying:

$\frac{5}{4k^{2}}$
