Question

Express as a positive rational numbers​

Answer 1

1/9

solution :-

${3}^{ - 2} = \frac{1}{ {3}^{2} } = \frac{1}{9}$

Answer 2

Answer:

1/9

Explanation:

Here the given number is 3^(-2)

To express this as a positive rational number.

We know that,

Any number in the form of p/q where p and q are integers and q≠0 is called a rational number.

Now, we know that,

a^(-m) = 1/{a^m}

Therefore, we have,

=> 3^(-2) = 1/{3^2}

=> 3^(-2) = 1/9

Hence, the required rational number is 1/9.
