If  x^(log_3  x − 1)   =  log_3  x + 3  Find:   log_3  x_1  + log_3  x_2  = ?
Ifxlog3x1=log3x+3Find:log3x1+log3x2=?

Where are x_1  and x_2  in your equation?

x_1 and x_2  are the probably two  solutions for the above euation

If you put Q/q and a number on the same  line then a link Q number is automatically  added by app

You can only approximate  x_1 ≈.555575  x_2 ≈7.18458  log_3  x_1  +log_3  x_2  ≈1.25994

Okay, since we are only interested in the logs  of x, we can reformulate the question as such:  x=log_3 x=ln(x)/ln3  witch gives:    If x_1  and x_2  are the two solutions of:  exp(ln(3)∙x ∙ (x−1)) = x+3             (eq_1 )  or  x ∙ (x−1) = log_3 (x+3)                         (eq_2 )  Find x_1 +x_2     I don′t know what you guys think, but  it sound a bit easier to deal with.  at least from my point of view...

x ∙ (x−1) = log_3 (x+3) can not be  solved exactly, only approximately.
x(x1)=log3(x+3)cannotbesolvedexactly,onlyapproximately.
