Step 1You can rearange these and put the &quot;x&quot; variables together.  (      x    2    )  ×  (      y    5    )  ×  (  x  )  =  (      x    2    )  ×  (  x  )  ×  (      y    5    )You can add the exponents of variables that you are multiplying, so add the       x    2   and the x. THe x is the same as       x    1   , so add the 2 and 1 to have the exponent of 3      x    3        y    5  You cannot combine different variables, so this is your final answer. C.

Step 1When multiplying variables with exponents any common variables are able to have their exponents added. y has no other common variable in the equation so it remains       y    5   . However there is an       x    2   and an       x    1   which becomes       x    3   . Therefore the answer is C.
