Best ResponseYou've already chosen the best response.1\[e^{x1}5=5\]Isolate e term.\[e^{x1}=10\]Natural log of both sides.\[lne^{x1}=ln(10)\]Properties of logatrithms.\[(x1)lne=ln(10)\]lne = 1.\[x1=ln(10)\]Solve for x.\[x=ln(10)+1\]

Best ResponseYou've already chosen the best response.1Is that \[5*6^{3m} = 20\]?

Best ResponseYou've already chosen the best response.1I'll assume it is, if it isn't, maybe the example will help you. \[5*6^{3m} = 20\]Divide both sides by 5\[6^{3m}=4\]Take natural log of both sides\[3m \ln 6 = \ln 4\]Divide both sides by \( 3 \ln 6\)\[m = \frac{\ln 4}{3 \ln 6}\]
