Hello! our answer here is going to be:
43.
Lets understand this a little better!
when dealing with exponents, it is the base number (3) times its self how ever many the above number is (3 again)
so, it wont be 3 x 3, but instead 3 x 3 x 3 because that's how much the exponent is.
same rule applies with 4^2!
