How do u say "how r u doing" in a more formal way?

Tell why you feel picasso is of such importance to the world. tell what period of his painting life you like best and why (choose one of his works of art that you really like, and tell why). be sure to use correct grammar, spelling, and punctuation in your writing (in either english or spanish). you will be graded on: -your ability to express your ideas. -your ability to use proper language skills.
