Looking at this term, the constant factors are five, seven, and two. So, we can write
those in the first three slots right here. Because of the commutativity of
multiplication it doesn't matter what order we write the five, seven, and two
in. Instead, I could have writen two, seven, five or two, five, seven or seven
five two or any order of these three numbers in these first three slots. For
simplicity sake, I'm just going to leave mine written this way, but you're answer
is right as long as these three constant factors are in these first three slots.
Now, what's left over to deal with are the variable factors. So for those, we have x,
y and z. Here, it's important to remember, the invisible multiplication signs between
these constant factors in the adjacent variables. Remembering that those are
there is what's going to allow us to pull out the variables and move them around.
So, I'm just going to keep x, y, and z in the order they're written in and fill them
into the slots right here. Now, just like with the constant factors, we could write
these variables in any order that we want to. We could write z,y,x, z,x,y, x,y,z,
actually, that's what we have, [LAUGH] y,x,z, . Any order these three variables
go in is correct as long as they are in these last three slots.
