Any non-zero number raised to the power of 0 is equal to 1. Therefore: 80=1 8^{0} = 1 80=1 Now, apply the negative sign: −(8)0=−1 -(8)^{0} = -1 −(8)0=−1
Any non-zero number raised to the power of 0 is equal to 1. Therefore: (−57)0=1 \left(-\frac{5}{7}\right)^{0} = 1 (−75)0=1 Now, multiply by 2: 2(−57)0=2×1=2 2\left(-\frac{5}{7}\right)^{0} = 2 \times 1 = 2 2(−75)0=2×1=2
The evaluated expressions are: −(8)0=−1 -(8)^{0} = -1 −(8)0=−1 2(−57)0=2 2\left(-\frac{5}{7}\right)^{0} = 2 2(−75)0=2
−(8)0=−1 -(8)^{0} = \boxed{-1} −(8)0=−1 2(−57)0=2 2\left(-\frac{5}{7}\right)^{0} = \boxed{2} 2(−75)0=2
