It's still no good without being able to find it with an actual calculator.
I am certain that I am supposed to solve the problem a certain way. The only lessons that specifically mentions calculators are the change of base lesson: Logb(A)=LogA/Logb= lnA/lnb, the common base lesson: b^M=b^N set bases equal I don't understand how my
How did you get .642538? When I type it in on my graphing calc, I get .707486674. The log base is 10. I get the same result with log(sqrt[x^2+1])
Is it .6949472936? by -3 and /-5 both sides by taking: loge^(-4x+2)=log .4585026652 then: (-4x+2)loge= log.4585026652 then: -4xloge+2log3=log.4585026652 then -4x(loge)=log.4585026652-2loge then -4x=-2.779789174 then divide by -4 to get .6949472936
