Answer:

Depends on what w is determined as, for example, if w = 4 then the answer would be 80

Step-by-step explanation:

Basically since there is a w next to the 5 we can make the equation 5 x w x w, since 4 = w, it makes the equation 5 x 4 x 4, next we can do 4 x 4 which gives us 16, you could also do 5 x 4 which equals 20, then we do 16 x 5 or 20 x 4 which equals 80 and there is your answer. This basically applies to all numbers as long as it is [number x w x w] and [w = number] no matter how you change the sequence you get the same answer.
