Help on Math test

So basically I got a math test back and it was about logs, i think some of the questions were marked wrong so im here to clerify.

1st question is simply this expression -4^-1/2 all over (-^-2/3
2nd question is evaluate the exponential function y = 10^x for the given value of x
x = -2/3

3rd question is expand: log with a base of 3[xa^2 over z^2]

4th question is Solve for y in terms of x: logy = logx-2log5 + 2
5th question is solve for x: Log with a base of 4 Sinx = -0.5

6th question is solve for x: 2e^(3x + 1)= 109.2

7th question is Solve for x: Inx-In1/3 = 1

Final question is Solve for x: log with a base of 8(x+2) = 2-log with a base of 8 2

Hope thats not too confusing
