Find the solution of the exponential equation: 19e^(x) - 7 = 2
What does x = ?
What does x = ?
-
19e^x=9
e^x=9/19
x=ln(9/19)
ln(9/19) plugged into a calculator is approx -.747214
e^x=9/19
x=ln(9/19)
ln(9/19) plugged into a calculator is approx -.747214
-
19e^x-7=2
19e^x=9
e^x=9/19
x=log(9/19)
x=log9-log19
x= 0.9542-1.2788
x=-0.3246
19e^x=9
e^x=9/19
x=log(9/19)
x=log9-log19
x= 0.9542-1.2788
x=-0.3246
-
19e^(x) = 9
x = ln(9/19) = -0.7472
x = ln(9/19) = -0.7472
