I am just confused with the question

Answer:
the correct option is 2....
Step-by-step explanation:
The given expression is:
-34 x² w^4 / 46 x^4 w^7
Firstly cancel out -34 and 46 by the table of 2
-17x² w^4/23x^4 w^7
Now it can not be cancelled further:
The next step is combine the like terms:
So we will move the variables of numerator to the denominator. The powers of the variables will become opposite
-17/ 23 x^4 w^7 x^-2 w^-4
Now solve the like terms. The powers of the same variables will be added.
-17/ 23 x^4+(-2) w^7+(-4)
-17/ 23 x^4-2 w^7-4
-17/ 23 x^2 w^3
Thus the correct option is 2....
