Answer

Problem

Determine the value of an expression when k = -3, l = -9, m = -2
\$ (k \times l)(l \times m)(m \times k) \$

Step

Now substitute k,l,m values in expression

\$ ((-3) \times (-9))((-9) \times (-2))((-2) \times (-3)) \$

Step

After multiplication

\$ (27)(18)(6) \$

Step

After multiplication we get

\$ 2916 \$
