I have been trying to figure this question out and I don't get it.

hints:

Commutative Property is important here. You can multiply these in any order you like.

a^2 is the same thing as a*a

a^5 is the same thing as a*a*a*a*a

The only two other factors of this statement are 2 & 5. The order of all these factors doesn't matter (commutative property of multiplication).

So the statement is the same thing as:

2 * (a * a) * 5 * (a * a * a * a * a)

= 2 * 5 * (a * a) * (a * a * a * a * a)

= 2 * 5 * a * a * a * a * a * a * a

= ....

If that doesn't help then let me know and I'll try again.

Well done.
