Simplify

3^2*3^-1/5^-2*2^0

To simplify the expression, we'll start by simplifying each individual term:

3^2 = 3 * 3 = 9
3^-1 = 1/3
5^-2 = 1/5^2 = 1/25
2^0 = 1 (any number raised to the power of 0 is equal to 1)

Now we can substitute these values back into the expression:

9 * (1/3) / (1/25) * 1

Multiplying the fractions: (9/1) * (25/1) * 1 = 225

Therefore, the simplified expression is 225.
