Best ResponseYou've already chosen the best response.0is that 7*3^(x1) or (7.3)^(x1)

Best ResponseYou've already chosen the best response.0do tell me..does this involve canceling 3^x1 the solution i thought had that..

Best ResponseYou've already chosen the best response.4@Ishaan94 that's true if the decimal was "dot" *

Best ResponseYou've already chosen the best response.0Oh, my bad... so it's \[(7.3)^{x1} + 53^{x+1}=0\]Hmm Now I feel stupid :/

Best ResponseYou've already chosen the best response.0I think 7.3 has something to do with 5, we should try to use 5

Best ResponseYou've already chosen the best response.0i meant he, meaning sam

perl

Best ResponseYou've already chosen the best response.0i think this could somehow become a quadratic, with the right substitution

experimentX

Best ResponseYou've already chosen the best response.0i don't think general method we use would work

experimentX

Best ResponseYou've already chosen the best response.0how do you solve this 2^x  x = 2

anonymoustwo44

Best ResponseYou've already chosen the best response.0I think we could only use newtons method......

anonymoustwo44

Best ResponseYou've already chosen the best response.0first we approximate an answer....

anonymoustwo44

Best ResponseYou've already chosen the best response.0then use the newton's method to get a better aproximation

anonymoustwo44

Best ResponseYou've already chosen the best response.0we continue this until we're satisfied

anonymoustwo44

Best ResponseYou've already chosen the best response.0but we can't still get the exact though :(

Best ResponseYou've already chosen the best response.0what is classic about this problem anyway?

satellite73

Best ResponseYou've already chosen the best response.0i assume that is \(7.3^{x1}\) and not \(7\cdot 3^{x1}\) so i have no ideas yet

satellite73

Best ResponseYou've already chosen the best response.0must be something special about 7.3 that i do not see

perl

Best ResponseYou've already chosen the best response.0can you guys tell me later, i gotta sleep

perl

Best ResponseYou've already chosen the best response.0ok try this , let u = 3^(x+1)

perl

Best ResponseYou've already chosen the best response.0i assume there is an exact solution, otherwise youve wasted my time

Best ResponseYou've already chosen the best response.4Sad thing for you @perl There's no exact solution but approximation \[7.3^{x1}=3^{x+1}5\]

Best ResponseYou've already chosen the best response.0i knew that newtoms method of approximation yesterday..

perl

Best ResponseYou've already chosen the best response.0it would be more interesting if there was exact solution , :(

perl

Best ResponseYou've already chosen the best response.0i was confused since you said it was easy problem , rats

perl

Best ResponseYou've already chosen the best response.0ok then how is it easy to approximate?

.Sam.

Best ResponseYou've already chosen the best response.4Its easy you don't even need to think, lol

perl

Best ResponseYou've already chosen the best response.0it didnt look easy on wolfram

Best ResponseYou've already chosen the best response.0sam , so are you going to post the solution or not. cuz im getting really tired

perl
 3 years ago
Best ResponseYou've already chosen the best response.0you can use a calculator for this. is that your 'easy' solution ?

.Sam.

Best ResponseYou've already chosen the best response.4you have to graph it for 7.3^(x1) and 3^(x+1)5 pick some points

perl
 3 years ago
Best ResponseYou've already chosen the best response.0what program do you use to graph that?

.Sam.

Best ResponseYou've already chosen the best response.4its a tedious job though, but if you have a graphing calc, it will be fine

perl

Mimi_x3

Best ResponseYou've already chosen the best response.0Newtons Method i think..

perl
 3 years ago
Best ResponseYou've already chosen the best response.0i dont think so, its just approximation problem

perl
 3 years ago
Best ResponseYou've already chosen the best response.0anyways, the question seemed pretty ambiguous. i didnt know what they meant by 'easy'

Mimi_x3

Best ResponseYou've already chosen the best response.0lol, thats all? guessing?

.Sam.

Best ResponseYou've already chosen the best response.4you can use this program to graph https://www.desmos.com/calculator/c

perl

Best ResponseYou've already chosen the best response.0then you do screen capture?

Mimi_x3

Best ResponseYou've already chosen the best response.0sigh..you can state your question as finding the approximation than 'solve for x'

.Sam.

Best ResponseYou've already chosen the best response.4@Mimi_x3 yes its a bit of disappointing, but I'll come up with a new question later :)

.Sam.

Best ResponseYou've already chosen the best response.4@perl no i dont screen cap on that software

Mimi_x3
 3 years ago
Best ResponseYou've already chosen the best response.0lol, i wanted to see a solution..but there is no solution *sigh*

.Sam.

Best ResponseYou've already chosen the best response.4the solution is approximation ,lol

perl

Best ResponseYou've already chosen the best response.0I think there is a confusion, he copied the problem originally with multiplication 7*3^(x1)
