To solve the expression 3^7 * 3^ -9, we can use the property of exponentiation which states that when you multiply two exponential expressions with the same base, you add their exponents.
Therefore, we have: 3^7 * 3^ -9 = 3^(7 + -9).
Since positive exponents indicate multiplication and negative exponents indicate division, we can rewrite the expression as: 3^(7 - 9).
Simplifying further, we have: 3^(-2).
Therefore, 3^7 * 3^ -9 equals 3^(-2), which is the answer in exponential form.
