Answer:
To simplify 7^3 * 7^-3, we can use the rule that states when you multiply two numbers with the same base, you add their exponents.
So, 7^3 * 7^-3 can be simplified as 7^(3 + -3) which is equal to 7^0.
Any number raised to the power of 0 is always equal to 1.
Explanation:
Therefore, 7^3 * 7^-3 = 1.
