these are extremely easy, let me tell you how to do them. You always have to do the question in the parentheses first, so for number 17 it would be 7 times the 10 power 7. When I say power, it’s the little number at the top of the whole number. You have to do 10 times 10 times 10 times 10 times 10 times 10 times 10. Then you get 10 million (10,000,000) now you do 10 million times 5, which is 5 million. So number 17 is 5 million. Now you can do the rest of them the same. When you have decimals, make sure to line them up. Good luck! Feel free to ask me any questions.
