The product of w and 12 is 12w.
w-8
That simply means that you divide w by 8. This can be written as w/8, or as (1/8)w.
8*w*w*w*w = 8w^4
1/w - 1 = - 8
What is the product for (-12)(-8)
8wwww = 8w^4
There can be no answer without further information about w.
W(1 + 1)
W+5y
It is: 2w which in algebra means 2 times w
w(a/b)
