Dubai, How to estimate HUGE numbers using scientific notation! (KristaKingMath)

► Subscribe to my channel // http://www.youtube.com/subscription_center?add_user=TheIntegralCalc ► Check out http://www.kristakingmath.com for more math help! :D In this video we'll learn how to use scientific notation to estimate the product of many large numbers multiplied together. We'll write each number in scientific notation, and then round each of the decimal numbers to the nearest whole number. Then we'll multiply all the whole numbers together to find their product. Then we'll multiply all the powers of 10, adding their exponents. Finally, we'll ensure that the final answer is written in scientific notation. ● ● ● GET EXTRA HELP ● ● ● If you could use some extra help with your math class, then check out Krista’s website // http://www.kristakingmath.com ● ● ● CONNECT WITH KRISTA ● ● ● Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;) Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!” So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.
