Am I wrong? Ya .. you miss it on that part :
to be 3^3x-2>1 we need 3x-2>=1,
you rather need it to be more than 0 , because 3^0=1 !!!!!!
so here is the solution ( just like you did , but replacing the 1 by 0)
3x-2>0 => x > 2/3 !!

M= 4^(1/2) + 4^ (1/3) + 4 ^ (1/4)
so basicaly U have to add 1/2 + 1/3 + 1/4 = 13/12 = 1+ 1/12
this will give U:
M = 4 ^ ( 1 + 1/12)
= 4^1 + 4^ (1/12)
= 4 + 4^ (1/12)
Thus: Answer is E
Hope that helps.

Answer: the combination that you can get here is: ( jasgua, José) or (José, Jashua)
so result is (1/6* 1/5) +(1/6 *1/5) = 2/30 = 1/15
now say that yuo have 3 people out of 6 that they will interview..
the result will be 3!( 1/6 *1/5 *1/4).
