c to the power of -4 x c to the power of 0 Is Zero right?
Or maybe the answer would be c to the power of -4 since c to the power of 0 would be 1.
Hmm

if i remember correctly if the power is 0 then it is zero.

Ok, I don't really understand well your typing :P
If you mean:
(c^-4)(c^0) *Being ^ equivalent to "to the power"
Then it is as you said in the text with the same color.
Remember that ALL powers give you magnitudes higher than 0 (it means that if you check the Absolute Value of your result, it will be always > 0)

Laws of powers:
xa*xb = xa+b and xa/xb = xa-b
"multiply, add; divide, subtract."
This also shows that x0 has to be 1, since xa*x0 = xa+0 = xa .
Hope that answers the question fully.

Unfortunately I had to figure this one out on my own since It was needed asap. Luckily though I picked the right answer, as explained by Fenix first. But nonetheless, I took a guess on It and now yall have provided me with future knowledge. Thanks!

Hope that answers the question fully.
Also note that:
(xa)b = xa*b and b-root(xa) = xa/b
Hope all these simple laws of powers help you in future assignments. :D

What field are we working in 0:)

looking back thru this forum...saw all these algebra problems...i'm in calc 3...so this is fun
anything raised to teh 0 power is one, therefore:
(c^-4)(c^0)
(c^-4)(1)
c^-4
