We have to match them, right?
I edited your question so it can be seen properly. Let's begin with: 4.2 × 105 and convert it into normal form. |dw:1370364139048:dw|
ty i was haveing a little bit of trouple getting it like that lol
Lol. No problem. Hope i help you out in learning this
yea alot :)
|dw:1370364276894:dw||dw:1370364285447:dw|Sorry made a mistake.
its ok :)
So for (a) we can see that it matches 420,000.
I want you to try b. 9.03 × 106
i got 957.18
Noo. 9.03 × 106 means that it;s written in this way: \[\Large 9.03 × 10^6\]
lol ok :)
Please see this video then try to attempt it. You'll be a boss at this then. ;D https://www.khanacademy.org/math/arithmetic/exponents-radicals/scientific-notation/v/scientific-notation-examples
Try it then. I'll check your answer.
hey i had watched the video and i had tryed the problem but i dont understand??
wait i think i found it out :P
Umm. Alright. So let me give you an overview. When we were given 4.2 × 10^5, it meant that some number is compressed and written into (scientific form). Now we have to unpack the number and write it in normal notation. Do you agree?
Alright. so 4.2 × 10^5, since the exponent is POSITIVE FIVE, we have to shift the decimal place FIVE times to the RIGHT. Agree?
the answer is 9,030,000 right :)
for 9.03 x 106
Awesome! You learnt it. Now when we have NEGATIVE exponent, we just have to move the decimal to the LEFT.
ok so i think for 9.03 × 10−6 it would be 0.00000903 right??
ok so the last one 4.2 × 10−5 would be 0.000042 right :P
