b) Consider the following definitions and answer the questions (10 points) def square root(x return math.sqrt def print_val (x) print (x) return i) What happens when you type in: print_val (square_root (4)) ii) which of the following are valid statements? Statement | y = square root(49.0) square root(10)=z y= 1.0 + square root(1440) | y = square root() square root(9.0) True or False (ie Valid or Not-valid) | y= 1 + print val(9.0) y = square root(square root(160) str3 = 'ABC' print val(10) z = str3"square root(4)
