Answer

Problem

Determine the value of an expression when f = 5, g = 4, h = -7
\$ (f \times g)(g \times h)(h \times f) \$

Step

Now substitute f,g,h values in expression

\$ (5 \times 4)(4 \times (-7))((-7) \times 5) \$

Step

After multiplication

\$ (20)(-28)(-35) \$

Step

After multiplication we get

\$ 19600 \$
