Answer:

1

Step-by-step explanation:

We have given expression 3^2\times 3^{-2}

We have to simplify the expression with use of property of exponent

According to property of exponent when two functions are multiplied with each other having exponent then their exponent are added to each other

So 3^2\times 3^{-2}=3^{2-2}=3^0

Now according to exponent property if 0 is the exponent of any number then its result will be 1

So 3^0=1
