if 5^n=x,find

hartnn (hartnn):

log x/ log 5

OpenStudy (anonymous):

the value of \[x^{-1/n}(\log_{5}x^{1/n}) \]

OpenStudy (anonymous):

i change the question to show that it is 1/5

OpenStudy (anonymous):

substitute 5^n for x and you should find your answer

hartnn (hartnn):

x^1/n = 5 so your final answer = 1/5

OpenStudy (anonymous):

yes it shuld give 1/5

OpenStudy (anonymous):

affirmative

OpenStudy (anonymous):

yes i made it myself,i am certain

OpenStudy (anonymous):

\[x^{-1/5}(1/n)\log_{5}x \] well we can invert both sides\[x^{-1/n}=1/5\], \[\log_{5}x=n \] so we have \[(1/5)(1/n)(n)\]

OpenStudy (anonymous):

=1/5
