In Exercises 81–85, use a calculator's factorial key to evaluate each expression. 20!/300

Accepted Answer

Welcome back. I am so glad you're here. We are given this expression 30 factorial divided by 225 and asked to evaluate it using a calculator. So I'm going to pull up google calculator here and show you what that looks like when we type it in. We'll have 30 factorial divided by 225. And we get this 1.1789016 E plus 30. So I'm going to copy that onto this screen. And so now we can round to the second digit in our decimals here. Round to the second place. The seven looks at the eight so that will round up to 1. and this E plus 30 means times 10 raised to the 30th power. Now we look at our answer choices and that matches with answer choice. A well done. We'll catch you on the next one.
