x=5^1/4 5^-1/4 y=5^1/4 - 5^-1/4 prove that 5(x² y²)²=144?
Examine the importance and impact of isomerism in
industry – research case studies in order to consider the
formation of different isomers during manufacture, how
their presence may influence the industrial process, the
differences in properties that they might have, and the
possible consequences of ignoring the presence of
isomerism.
Question 1
Write down the method isPrime(int number), which accepts an positive integer and return a boolean
value if the number is Prime or not.
Question 2
Write a method called printUnique that accepts one integer array as argument, and print all unique elements
form the array. E.g. {5,6,7,8,9,8,7,6,5} (9 is unique).
Question 3
Given two arrays of same size and type, arr1={1,2,3,4,5} and arr2={6,7,8,9,10} calculate the
difference of all values in the array and your operation would be like (Arr2 - Arr1)
