Hi I don't have time to type each question on the answerboard if you answer it in different blocks I will rate you lifesaverplus helpful for every answer thanks my test is tommorow so I need urgent help!!! please show me step by step if you can 1. In x = 2.7 2. In (x+1)=1.86 3. x = e9.8 / e7.6 ?? Would this just bee2.2 4. 6.27 = ex 5. 4.12= e-2x please show step by step thanks alot!!!

Explanation / Answer

I assume you're just solving for x. 1) ln x = 2.7 To get rid of the natural log, take the exponential function (e) ofboth sides. elnx = e2.7 x = e2.7 x = 14.88 2) Same thing as above, take e of both sides. ln (x+1)=1.86 eln(x+1) = e1.86 x+1 = e1.86x+1 = 6.42 x = 5.42 3) yes, that is right 4) To get rid of the e, you do the opposite of what you did in 1and 2 by taking the natural log of both sides. ln 6.27 = ln (ex) ln 6.27 = x 1.84 = x 5) Same thing as above x = -.71
