Best ResponseYou've already chosen the best response.0use log property: log x +logy = log xy and log x^n = n*log x > log base 4 (3^2 *2) = log base 4 (18)

Best ResponseYou've already chosen the best response.0Well without a calculator log base 4 of 2=1/2. And 2 log base 4 of 3 can be written as 2 log 3/log 4(Both to base 10) Log 4=2log 2 so it becomes log 3/log 2(Which values it think you should remember )=0.4771/0.3010. So it becomes 4771/3010+ 0.5
