The algebraic expression x • y • z = y • x • z exhibits the transitive property. Transitive property is applied when rearranging the elements or numbers within a term such that the answer or value is still the same. Transitive property is useful in factoring procedure.
Answer:
(^6√x^5) (√y)
(The 6 belongs in the left on top of the square root btw)
For x the 6 moves to the front of the square root while the 5 becomes the power of x.
For y, the power to the 1/2 is the same as a square root.
If

is left, that means

was spent. So

of the total amount is equal to 39.. Let's say x to the total amount.
