Question

( 0-9^{n}-6 cdot 3^{n}+8= )
Prot ( 3^{n}=+ )
( t^{2}-6 t+8=0 )
( t^{2}-2 t-4+18= )
( (+-2)(t-4)=0 )
( t=2+-4 )
( 2^{n}=2 quad 3^{n}=4 )
( x log 3=log 2 quad ). ( x log 3=2 log 2 )
( frac{log _{2} 2}{log 3} cdot 2=frac{log _{2} 2}{log _{2}} )
( n+n_{2}-3 log _{3} 2 )

# N The sum of the solutions of the equation 9x -6.3+ 8 = 0 is (A) log, 2 (B) log: 6 (C) log: 8 (D) log3 4
