Algebra help 2

posted by .

Where appropriate, include the approximation to the nearest ten-thousandth.
27.) log x = -3
I have the answer as -3

28.) 7 ^(4-9x)= 49 I have the answer as 2
29.) 8^x =5.2 not sure
30.) 1n x=5/8 not sure

Are these answers right?

    27. Nope.

    what is the log of 1/1000?

    28. log base 7 each side..
    4-9x=2
    solve for x.

    On the last two, I see no easy way to approximate. I will think on them.
