There is no work to show little Kathy.

Take the square root of both sides to get rid of the exponent.
sqrt(z^2) = sqrt(121)
z= sqrt(121)
z=+11 or -11

my god - you really need to study or pay attention in class. Read your textbook, try to solve the problem and then check the answer in the back of the book.
