Hey there! :D

With negative exponents, you make them into fractions to get rid of the negative.


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

Now, just square the bottom.


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

Next one.


2^(-2) = (1)/(2^2)

Now, square the bottom.


(1)/(4) = (1)/(2^2)

Now, we have:


(1)/(9) + (1)/(4)

Make a combine denominator of 36.


(1)/(9) = (4)/(36) \\\\(1)/(4) = (9)/(36)

Now, add them together.


=(13)/(36)

I hope this helps!
