Zero, because ANYTHING to the power of zero equals 1.
Can I get a new photo, I would gladly answer all of them for you
C because when you expand all the numbers, they go in the same order as c has them.
Did the question give you any lengths of the sides?
The given information is,
→ a = -8
→ b = -7
→ c = 6
Let's verify the problem,
→ (a+b) + c = a+ (b+c)
→ (-8 - 7) + 6 = -8 + (-7 + 6)
→ -15 + 6 = -8 - 1
→ -9 = -9
→ [ LHS = RHS ]
Hence, it is equal and verified.
