Question

What is the value of st (6r) if r = 5,s = 32, and t = 45

Answer 1

st(6r)
(32)(45)(6(5))
1440(30)
43200

Answer 2

Well, the parentheses don't need to be there since it's all multiplication. 6str would work the same way. substitute each variable in the equation for what it should be.
6*5*32*45.
30*32*35
43,200 is the answer.
