Please answer questions 4-8 on a piece of paper with answer very clearly written so that I can copy it all and submit it. If you submit answer through app and not submitted through picture written on paper I will not understand it. Write it as if you were doing the exam yourself. Thanks ! :)

4. Combine 3 In x + 2 Iny + 7 Inz -5 In w, i.e. rewrite the expression as a single logarithm. 5. Fully expand log( 100x-Sy3). In particular, your final answer should contain no exponents, and if there is any component that you can numerically evaluate, do so. 6. Let f(x) = 7esx+5 - 2. Find a formula for the inverse function /(x). (Set f(x) equal to y, switch the variables and solve, etc.) 7. Find the domain of the function h(x) = In(3 - x). Give your answer in interval notation. B. Give the exact solution to the equation (no decimal approximation-meaning don't use a calculator). (a) 10' =3 (b) 2" =3 (c) ex =3 (d) log x =3 (e) log, x = 3 (f) Inx = 3 2
