Hi class!!! I don't know very weel what I have to do but I go to start.
Today in class we studied the Scientific Notation.
A number with a scientific notation has always two parts:
- A decimal number n verifying that _
- A power of 10 with an integer number as exponent.
For example: 300.000.000= 3·108
Then we have done some exercise about the scientific notation,that are: Page 42 (13-15)
13.a)493000000= 4'93·108 d)12'00056= 1'200056·10
b)315000000000= 3'15·1011 e)253=2'53·102
c)0'0004464= 4'464·10-4 f)256'256= 2'56256·102
14.a)0'247·108/ 2'47·107
b)24'7·108/ 2'47·109
c)0'247·10-8/ 2'47·10-9
red= important things
blue= the exponents
I think that that's all:))
I put some videos to entertainment:P

It is very strange that Mario hasn´t comment yet. AJjajaja good post
ReplyDeleteI've just arrived home!
ReplyDeleteWell done Zuriñe! ;)
Next Monday we're going to review the operations involving scientific notations, and after that we may play a little game :D
JAAjaaj what game? Is monday the strike?
ReplyDeleteSURPRISE.
ReplyDeleteTristán, today we've been summoned to gather on a concentration at Antonutti's Park at 17.30. The general strike is set to be next Thursday ;)
Today I´m not going to go to the strike. It´s boring!!!!!!!
ReplyDeleteI've finished my studies a few years ago, so it's your education the one that's ind danger, not mine... The choice is up to you all!
ReplyDeleteMy mother went yesterday to the strike. It is also your education because you work in it!
ReplyDeleteThere is homework?
ReplyDeletei think that it is not homework
ReplyDeleteYou're right, there's no homework :)
ReplyDeletemario, can you tell me the homework of today?
ReplyDeleteHi Allo! How are you? I hope you just got the flu, or something similar... ;)
ReplyDeletePaula is the one who's going to create today's entry :D but I can summerize it for you ;)
1) First we reviewed the exercices you gave me last week.
2) Then we learned how to operate (+, -, x, :) numbers involving scientific notation (it's very easy).
3) Finally, we (tried to) play(ed) a MEMO game with scientific notation quantities ;)
I only asked you to do one exercice for tomorrow: exercice 70 ;)
ok thank you. i'm bad. "seguramente" I won't go to class the next days because i've a "neumonia"
ReplyDeleteajajjaj exercise 70? exam??????????????????
ReplyDeleteOMG!! Neumonia... what a terrible disease!
ReplyDeleteDon't worry! Take care of yourself ;) I hope to see you soon back in class :D
than you :)
ReplyDeletecan you give me the exercises that they have been doing these two days?
I was told that you gave a voluntary paper with exercises.
ReplyDeleteif you have it in the computer, can you send it to my email? (allo.radejo@gmail.com)
Hi Allo! I hope you're feeling better today :)
ReplyDeleteRuben is supposed to create today's entry explaining what we did today :D but don't worry, I'll send you the "theory" sheets we've worked with this morning and that bulletin :)
That bulleting is nothing but a recopilation of exercices involving scientific notation, approximation and errors. I'll upload the solutions next monday (if you print it you'll have enough space to do the exercices in the page :D )
Remember that it's just a practising bulleting and you're not supposed to give it to me ;)
yes i feel better today :)
ReplyDeletethank you for the email.
i will try to do the papers.
i've already seen the entry of ruben.
