Question

if 6 power x =30 rhen what will be value of 6 power x-1 + 6 power x+1 =

Answer 1

${6}^{x - 1} + {6}^{x + 1} = \frac{ {6}^{x} }{6} + {6}^{x } \times 6 \\ {6}^{x} \times ( \frac{1}{6} + 6) = 30 \times \frac{37}{6} = 185$

Answer 2

6^x=30
ln6.x=30
x=ln30/ln6
ln6(x-1)+ln6(x+1)
2ln6.x
put value of x
2ln6.ln30/ln6
2ln30
