Where appropriate, include the approximation to the nearest tenthousandth.
27.) log x = 3
I have the answer as 3
28.) 7 ^(49x)= 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?

bobpursley,
27. Nope.
what is the log of 1/1000?
28. log base 7 each side..
49x=2
solve for x.
On the last two, I see no easy way to approximate. I will think on them.
