Question

$4^{\frac{1}{x}-2}= \frac{(ln \sqrt{e})}{2}$

Answer 1

\[4^{\frac{1}{x}-2}= \frac{(ln \sqrt{e})}{2}\]

(If you put \ [ and \ ] (no spaces) instead of $ around your expressions it should format them)

Answer 2

Why not take the log of both sides, then solve for x?

Answer 3

Remember that \[\log a^n = n \log a\]

Answer 4

Also, try writing that radical sign with exponential notation instead and see if any ideas come to you...

Answer 5

Don't forget that \(a^{-n} = \dfrac{1}{a^n}\)
