Best ResponseYou've already chosen the best response.0OK ... \[5^{x  3} . 3^{2x8} = 225\]

Best ResponseYou've already chosen the best response.0How to solve this using log? I'm new so I have no idea.

Best ResponseYou've already chosen the best response.0I guess you can solve this without using Logs..

Best ResponseYou've already chosen the best response.0But I want to know how to do it with log.

Best ResponseYou've already chosen the best response.0Okay then all here will explain you how to do this...

Best ResponseYou've already chosen the best response.015^(x3)+(2x8)=225 now we take ln (3x11)15= ln225

Best ResponseYou've already chosen the best response.0What is In? And how did you get 15^(x3)+(2x8)=225?

anonymous

Best ResponseYou've already chosen the best response.0by multi 3 into 5 to get 15 and the exponent it's added

anonymous

Best ResponseYou've already chosen the best response.0But how can you just multiply the base and add the exponents?

anonymous

Best ResponseYou've already chosen the best response.0Use the following formulas of Logs: \[\large Log(a \times b) = Log(a) + Log(b)\] \[\large Log(a)^b = b.Log(a)\]

Best ResponseYou've already chosen the best response.0See, take Log both the sides you will get: \[\large Log(5^{x3}.3^{2x8}) = Log(225)\] Now use the formulas I have written above..

anonymous

Best ResponseYou've already chosen the best response.0Use the first formula only...

anonymous

Best ResponseYou've already chosen the best response.0\[\log(5^{x3}) . \log(3^{2x8}) = \log 225 \]

anonymous

Best ResponseYou've already chosen the best response.0Now Check my first formula carefully...

Best ResponseYou've already chosen the best response.0like what waterineyes did now

anonymous

Best ResponseYou've already chosen the best response.0That's what I've done here right @waterineyes?

anonymous

Best ResponseYou've already chosen the best response.0I give you an example: \[\large Log(2 \times 3) = Log(2) + Log(3)\] Go by this procedure...

anonymous

Best ResponseYou've already chosen the best response.0I've already done that. So now we should use the second one?

anonymous

Best ResponseYou've already chosen the best response.0You have done it wrongly my friend...

anonymous

Best ResponseYou've already chosen the best response.0See check the formula.. After formula the result will be in sum form and your result is not in sum form.. Is there any + sign in your result???

anonymous

Best ResponseYou've already chosen the best response.0Oops. \[\log(5^{x3}) + \log(3^{2x8}) = \log225\]

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0Yes now you are right... Now 225 is square of what number???

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0So can you write 225 as \(15^2\) on right hand side.?? If yes then do it..

anonymous

Best ResponseYou've already chosen the best response.0\[\log(5^{x3}) + \log(3^{2x8}) = \log15^{2}\]

anonymous

Best ResponseYou've already chosen the best response.0Now use the power rule of Logarithms that is the Second Formula that I have given above.. Can you use that??

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0I give you an example of that too: \[\large Log(x)^4 = 4.Log(x)\]

anonymous

Best ResponseYou've already chosen the best response.0\[(x3)\log5 + (2x8)\log3 = 2\log15\]

anonymous

Best ResponseYou've already chosen the best response.0Can you write 15 as 3*5??

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0Yes. \[(x3)\log5 + (2x8)\log3 = 2\log(5 * 3)\]

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0Then use it and use the first formula again on right hand side...

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0\[(x3)\log5 + (2x8)\log3 = 2\log5 + 2\log3\]

anonymous

Best ResponseYou've already chosen the best response.0Now what you have to do is to compare the coefficients of \(Log3\) and \(Log5\) both the sides can you do that??

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0Tell me the coefficient of Log3 on Left hand side and right hand side...

anonymous

Best ResponseYou've already chosen the best response.0On LHS its 2x  8 and on RHS its 2.

anonymous

Best ResponseYou've already chosen the best response.0Just equate them and find x from it..

anonymous

Best ResponseYou've already chosen the best response.0Similarly equate the coefficients of log5 and then also find x you will get the same x in both the case...

anonymous

Best ResponseYou've already chosen the best response.0\[(2x8)\log3 = 2\log3\]

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0I said to equate the coefficients buddy.. Coefficients are 2x  8 and 2.. you should equate this only...

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0So you should just do 2x8 = 2?

anonymous

Best ResponseYou've already chosen the best response.0See, if : \[\large xlog3 = ylog3\] implies x = y. Getting??

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0Yes you have found x = 5 that is absolutely right...

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0Now equate the coefficients of log5..

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0x  3 = 2 x = 2 + 3 = 5

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0Yes got the same value of x so you are right.. If anyhow x values are coming different then either question is wrong or your solution is wrong.. Getting??
