okaayy... Firstly, let's break this down into parts :) Note that : |dw:1439908922717:dw|
what does 3/4 equal to as a decimal?
great! So we now know this: |dw:1439909078119:dw| Now, what would 0. 75 equal to in scientific notation?
Sorry, I dunno :/
do you know what scientific notation is?...
not really, my teacher just gave me all this stuff i know nothing about
okaayy.... xD Err, maybe you should try to understand how scientific notation works: https://www.mathsisfun.com/numbers/scientific-notation.html But basically you want to re-write 0.75 with the decimal after the first digit which would be 7 in our case right? So we want 7.5 TIMES 10 to a power. 0.75 = 7.5 x 10^-1 Following??
|dw:1439909465669:dw| |dw:1439909508652:dw| Now you have to use your exponent laws. |dw:1439909579654:dw|
Therefore, if we use the exponent rules in the box, we will get: |dw:1439909682894:dw| What does -1 + 20 - 5 = ?
goood! And we're done! TA DAAA~|dw:1439909773035:dw|
thx, :D but can i send you some of my other question to see if i got the right answer?
you're welcomeee! Hmm.. how many questions? I'm about to head off to bed so xD..
those are all
question 1. correct question 2. correct question 3. incorrect. btw, you're pictures aren't in order... :)
i know, i screen shot them and uploaded in the wrong order ;P what's wrong with 3??
See how they are both 10^20? This means you just add the 3.7 and 4.45 part ... So like.. say x = 10^20 We have 3.7x + 4.45x = 8.15x if that makes sense?
thanks alot dude :D
no woorries ! Anyways, night
