What is the value of 7^0?

Explanation:
Any nonzero number raised to the power of zero equals 1. This comes from the exponent rule a^m / a^n = a^{m-n}; if you set m = n, you get a^0 = a^m / a^m = 1. So 7^0 = 1. The other options don’t fit: 0 would require a different rule, 7 would be the value if the exponent were 1, and 1/7 corresponds to an exponent of -1 or taking a reciprocal.
