Write the following in the terms of log 5 log 3 and/or log 2

Question

1) log 5/12

write the log equations for each then solve using logs 

2) x=5th square root (72.43)*3rd square root (.00035)^2 divided by the 6th square root (5.84)

3)2.35^x=342.7

Answer 1

1) log(5/12) =about -0.038

but (log5)/12 = about +0.06

2) (72.43^.2)* then it's hard to makes sense of the question "3rd square root"??

3) 235^x = 342.7

xlog235= log342.7

x = log342.7/log235 = about 1.0691
