Interets Composes:

Un capital de 4500000 LL est place, a interets composes au taux de 10.5% pendant 4 ans. Trouver la valeur acquise.

Solution:

Capital (c) = 4500 000
Interet(I) = 1 LL x 10,5% = 0,105
Duree (n) = 4 ans
Valeur acquise = Capital + Interets

La formule generale est:

A= C(1+I)4
A= 4.500.000(1,105)4

Log(A) = log(4.500.000) + 4 X log(1,105)
Log(A) = 6,653.21 + (4 x 0,04336)
Log(A) = 6,826.65
A = 6.708.880 LL :crazy:

I knew how it all works but i couldn't know from where we got the result i reached (Log(A) = 6,826.65) and 3ela2et.

actually bro, i still remember it ALMOST... its while using ur Scientific calculator.. after reading ur post, i lost btw dividing the "." from the "," so here it goes again:

Log(A) = log(4 500 000) + 4 X log(1,105)
Log(A) = 6,653212514 + (4 x 0,043362278)
Log(A) = 6,653212514 + 0.173449112

= 6,82661626

, -----> VIRGULE

was ur answer copied from ur notebookO_o ? cuz betkun ghalbatot while copying men kam exercices maktoubin 3al tableau.. rez2alla lamma kenit Joumana ma3na.. she used to write everythin:(

cuz i used the calcutlator n that's what i came out with, im not that gd in Maths (financial n Generale) bas im gr8 in Comptabilité + Analytiques:D so im sure u have some questions related to 'em

Justin this is from the math book.
Everything is correct i just didn't know from where we got the result the one in red.

Ya dany ya TRAIN !
A= C(1+I)4
A= 4.500.000(1,105)4
A = 6.708.880 LL
:'( i wonder why u didnt pass last year :p iza bedak 7adan ydarsak de2eleh mc :p

loooooooool sarah that wasn't so smart i want it the log way :P
i know how to do it this way :(
As for the last year i didn't go for the official exam (who knows) :D

I think we should convert the log in a way to get the original value not log(ed).

This Thread is consider as a help issue for Everyone who's facing problems in studying BUT WE DO NOT SOLVE UR HOMEWORKS or TMAs... or else i would've posted mine:(

Log(A) = 6,826.65
Log(A)= Log 10 6,82665
(A)=10^6,82665= 6.708.880 LL

log a = x
a= 10^x

I'm smart !:p
A= 10^6,826.65=6.708.880 LL

Gosh i love maths !:D

Sarah you're such a liar :P
Thanks enigma :D i love you!
Ok now close the subject i won't be late by posting another one. take it as a game :)
