Practical Exercise 3 (1) What is the value of this arithmetic expression? (-$x*$y+ $val[23]*$x-2.5)/($x+$y-Sx*Sy+38.5) Assume that $x, Sy and $val[23] are 4.5, -2 and 3.0 respectively. (2) Why is this assignment statement invalid? $res = "the value is ".$x+$y." pounds"; (3) What is the value of this logical expression? $x && $y XOR (SxlI$y) Assume that $x is TRUE and $y is FALSE (4) Write a For loop to output the squares of the first 20 even numbers. (5) Given an array of numbers $numbers and a variable $val write PHP statements to output the position of Sval in array $numbers or a statement that it is not in the array. Do this (a) using a While loop and (b) using a Do...While loop. (6) Write an If statement that takes a variable $month containing the name of a month, e.g. "October", and outputs the number of days it contains.
