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.

27.) x=1

28.) I have x= 2/9

Not sure about the last two

29.) 8^x =5.2 not sure

30.) 1n x=5/8 not sure
