Question

In Exercises 77–86, write each number in scientific notation. −3829

Accepted Answer

Welcome back. I'm so glad you're here. We are expressing the number 91 million. 980,000 in scientific notation. So to get that into scientific notation, only the left most number is now going to be to the left of the decimal points. So we're going to rewrite that as nine point and we're going to carry down all the numbers up until we hit the wall of zero. So we'll bring down the one the nine and eight. And we're going to leave off those zeroes in our new decimal number. And next we're going to multiply that times tend to that and there's going to be an exponents. And the exponents is asking how far did we move the decimal place from where it used to be? And we moved it spaces. So that's going to be 9.198 times 10 to the seventh. We look at our answer choices and this is answer choice B. Well done. You've done. It will catch you on the next one.
