what makes the statement true? 9^-2=?
The statement is not complete and requires to be solved.
9^-2= 1/9^2 = 1/81.
Therefore, the complete statement is 9^-2= 1/81.
To determine the value of 9^-2, we need to understand how exponentiation works.
When a number is raised to a negative exponent, it means that the number is being inverted or reciprocated. So, 9^-2 can be written as 1/9^2.
To find the value of 1/9^2, we need to evaluate 9^2 first.
9^2 means 9 multiplied by itself, so 9^2 is equal to 9 * 9, which is 81.
Therefore, 1/9^2 is equal to 1/81.
Hence, the statement 9^-2 = 1/81 is true.
