B) Log x 3/2=-2 ==> x = (3/2)^-2 ==> x = (2/3)^2 ==> x = 4/9
=======================================================
C) log x √2= 3/2 ==> 
x = (√2)^3/2 ==> x = (2^1/2)^3/2 ==> x= 2^3/4
=======================================================
D) log x 1/8 = -2/3 ==> x = 
(1/8)^-2/3 ==> x = (8)^2/3

==> x= (2^3)^2/3 ==> x= 2^6/3 ==> x = 2^2 ==> x = 4
