## Simplifying (9/7)^-2 without Exponents

The expression (9/7)^-2 may seem intimidating at first glance, but it can be simplified using basic exponent rules. Here's how to break it down:

### Understanding Negative Exponents

A negative exponent indicates the reciprocal of the base raised to the positive version of the exponent. In simpler terms:

**x^-n = 1/x^n**

Applying this to our expression:

**(9/7)^-2 = 1/(9/7)^2**

### Simplifying the Expression

Now we need to square the fraction (9/7):

**1/(9/7)^2 = 1/(81/49)**

Dividing by a fraction is the same as multiplying by its reciprocal:

**1/(81/49) = 1 * (49/81)**

Finally, we get:

**(9/7)^-2 = ** **49/81**

Therefore, (9/7)^-2 without exponents is simply **49/81**.
