log4(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.
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.
