Natural Log problems? Please help?
Use Natural logarithms to solve each equation:
2.) 3e^3x-5=49 (the minus 5 is in the exponent)
3.) 7e^5x+8=0.23 (the plus 8 is in the exponent)
4.) 3ln e^2x=12
5.) e^x+6 +5=1 (the plus 6 is in the exponent and the plus 5 is seperate and not in the exponent.)
I dont understand these problems at all and I have a quiz on them tomoorrrow. Please help by solving and explaining. Thanks
