4(3n-2)^(-3/2)+1=347/343
blagie [28]
Greetings and Happy Holidays!

Solve for n.
4(3n-2)^{\frac{-3}{2}}+1= \frac{347}{343}

Add -1 to both sides.
(4(3n-2)^{\frac{-3}{2}}+1)+(-1)=(\frac{347}{343})+(-1)

4(3n-2)^{\frac{-3}{2}}=\frac{347}{343}-1

4(3n-2)^{\frac{-3}{2}}=\frac{347}{343}-\frac{343}{343}

4(3n-2)^{\frac{-3}{2}}=\frac{4}{343}

Divide both sides by 4
\frac{4(3n-2)^{\frac{-3}{2}}}{4}=\frac{\frac{4}{343}}{4}

\frac{4(3n-2)^{\frac{-3}{2}}}{4}=\frac{4}{343}(\frac{1}{4})

\frac{4(3n-2)^{\frac{-3}{2}}}{4}=\frac{4}{1372}

\frac{4(3n-2)^{\frac{-3}{2}}}{4}=\frac{1}{343}

(3n-2)^{\frac{-3}{2}}=\frac{1}{343}

Solve the Exponent.
((3n-2)^{\frac{-3}{2}})^{\frac{2}{-3}} =\frac{1}{343}^{\frac{2}{-3}}

3n-2=49

Add 2 to both sides.
(3n-2)+2=(49)+2

3n=51

Divide both sides by 3.
\frac{3n}{3}= \frac{51}{3}

n=17

The Answer Is:
\left[\begin{array}{ccc}n=17\end{array}\right]

Hope this helped!
