    • @wendyrios6735
      @wendyrios6735 4 роки тому +19

      @@jomanaelarabi6380 You have to move the 2 decimal places to the left in order for 612 to convert into 6.12 (that's bc the integers have to be greater than or equal to 1 and less than 10) and by moving the decimal to the left the exponent increases by 2 bc you moved 2 decimal places to the left! :D hope that helped

      Yeah, you should be good but in case you ever need more practice problems or a better explanation, I create how-to guides that seriously cut your study time in like half. I know how confusing the textbook can be, that's why I created these guides. You can find all my guides here melissamaribel.com and I have a guide specifically for this topic of unit conversion/ dimensional analysis. Here's the link: melissa.help/sigfignotes

      She said she made a typo it's supposed to be 6.12*10^5 or 612000. It's the same thing, one is just written in scientific notation. If you have a graphing calculator you can change the mode to scientific and it will give you the answer written that way

      If everything had the same base unit or meters yes, so if we were going from cm to dm or mm to km.

      @fridadavila1561 3 роки тому

      I’m on the same bot as you.. but i got 1.738x10^0 I’m not sure what I’m doing wrong... But to answer your question if you are using a TI-30XllS (my calculator) you want to switch the settings by pressing the “2nd” button it should be on the top left and next to it there’s a button called “DRG” after you press the 2nd and the DRG button there’s an option that says “SCI” press that and put enter on your calculator so it saves what you just switched and when you do the problem you put in 1738 x (press the “2nd button) and the button bellow it that says “log” it will automatically input to 10 all you have to put is the 3 and I close the parenthesis and it will give you the answer. It’s a lot of information but hope it helps

    For the 1.738x10^6m answer, can we round up to 1.74x10^6m?

    Hi Melissa, I am so glad I found your channel, chemistry us starting to make sense to me now XD but I am just wondering how did you get 10^-7 for the last conversion, I am looking at the metric table and can't see it. Thanks !
