The correct answer is 1/9, 0.111, .111.
To solve the equation log3x = -2, we need to rewrite it in exponential form. Since the base of the logarithm is 3, we can rewrite it as 3^-2 = x. Simplifying this, we get x = 1/9. Therefore, the answer is 1/9.
Additionally, 1/9 can be expressed as a decimal, which is 0.111 when rounded to the thousandths place. Hence, both 0.111 and .111 are also correct answers.
