3^7 x 3^-9
To simplify 3^7 x 3^-9, we use the rule of exponents which states that when multiplying two numbers with the same base, we add their exponents.
So, 3^7 x 3^-9 = 3^(7 + -9).
The sum of 7 and -9 is -2, therefore the expression simplifies to 3^-2.
However, for a positive exponent, we know that 3^(-2) = 1 / 3^2.
So, 3^-2 = 1 / 3^2 = 1/9.
Therefore, 3^7 x 3^-9 = 1/9.
