**drwls**, Saturday, March 29, 2008 at 12:58pmlog4(m-3)+ log4(m+3) =2

log4[(m+3)(m-3)] = log4(m^2-9) = 2 = log4(16)

m^2 -9 = 16

m = 5

<<Use common logarithms to approximate log9(207) to four decimal places.

Answer: 2.4270>>

log9(207)*log10(9)= log10(207)

log9(207) = 2.31597/0.95424 = 2.4270

I don't have time to do all 10. Fewer questions per post would be appreciated, even it you just want them checked.
