Thread: Estimating each log expression

Problem reads: Use log 7=.8451 and log 4= .6021


a.) log 7/4
I know that --> = log 7 - log 4

So, would I do this, .8451 - .6021, or divide?

Thanks.

you would simply subtract them of course, you said it yourself, why would you think of dividing if the rule says to subtract?
