What is the purpose of the return statenent? = TASKS = 1. Write a new function to multiply two numbers together and return the result = 2. Write a neu function to divide two nunbers and return the result. Run the progran and try entening '0' as the second number what happens? How COuld you fix this? = 3. Write a nen function to display a menu whích should allou the user to change the numbers or choose which operation they would like to perform, e.g. choose from addition, multiplication, etc = 4. Modify your menu function to include an option to exit the program and add a loop to allom the user to restart the program until they choose the exit option E 5. Write a neu function which takes two argunents, a number and a power and returns the numbertpower. You should research and use the math.pow() function to do this. What is the difference between nath.pow() and **? E6. Write a new function which takes two arguments, a number and the nth root (e.g. 2 would be square root, 3 cubic root, etc) and returns the nth root of the number. You should research an appropriate way to do this

# QUESTIONS # 1. Why are the parameters x and y used in the function definitions rather than first_num/second_num? # 2. What is meant by local and global scope of variables? # 3. What is the purpose of the return statement? # TASKS # 1. Write a new function to multiply two numbers together and return the result # 2. Write a new function to divide two numbers and return the result. Run the program and try entering '0' as the second number, what happens? How could you fix this? # 3. Write a new function to display a menu which should allow the user to change the numbers or choose which operation they would like to perform, e.g. choose from addition, multiplication, etc # 4. Modify your menu function to include an option to exit the program and add a loop to allow the user to restart the program until they choose the exit option # 5. Write a new function which takes two arguments, a number and a power and returns the number^power. You should research and use the math.pow() function to do this. What is the difference between math.pow() and **? # 6. Write a new function which takes two arguments, a number and the nth root (e.g. 2 would be square root, 3 cubic root etc) and returns the nth root of the number.
