Question

In Exercises 87–106, perform the indicated computations. Write the answers in scientific notation. If necessary, round the decimal factor in your scientific notation answer to two decimal places. 282,000,000,000/0.00141

Accepted Answer

Welcome back. Let's look at our next problem, perform perform the indicated operation and expressed the answer in scientific notation. And we have the number 384 million divided by .0000192. So the easiest way to approach this. Since we want to get to an answer in scientific notation is to convert our problem into scientific notation. So on the top here are 384 million Becomes 3.84 times 10 to the let's move our decimal . 10 to the 8th power. and on the bottom we'll have 1. times 10 to the 12345 -5. And this is a division problem. So we need to subtract the exponents. So first we're going to divide 3.84 by 1.92. And that answer is exactly two Times 10 to the and then it will be - and -5 so that will equal two times 10. So eight minus negative five is eight plus five. So 10 to the 13th power. So our answer here is two times 10 to the 13th power which is choice d. here. And we can double check that because we had a very large number that we divided by a very small number. We subtracted a negative exponent. So we expect to see our answer to be a larger number. That exponent grow larger. So just double check that that answer makes sense. So choice D2 times 10 to the 13th power. See you in the next video.
