Answer:
Isolate exponential term:
Isolate the exponential term by dividing both sides of the equation by
88
88
88
.
\newline
88
e
x
88
=
48
88
\frac{88e^x}{88} = \frac{48}{88}
88
88
e
x
=
88
48
\newline
e
x
=
48
88
e^x = \frac{48}{88}
e
x
=
88
48
Simplify fraction:
Simplify the
fraction
on the right-hand side of the equation.
\newline
e
x
=
48
88
=

e^x = \frac{48}{88} = \frac{6}{11}
e
x
=
88
48
=
11
6
Take natural logarithm:
Take the natural logarithm of both sides to solve for x.
\newline
ln
(
e
x
)
=
ln
(
6
11
)
\ln(e^x) = \ln\left(\frac{6}{11}\right)
ln
(
e
x
)
=
ln
(
11
6
)
\newline
x
=
ln
(
6
11
)
x = \ln\left(\frac{6}{11}\right)
x
=
ln
(
11
6
)
Use calculator:
Use a calculator to find the value of the natural logarithm of
6
6
6
/
11

.
\newline
x
=
ln
(

x = \ln\left(\frac{6}{11}\right) \approx -0.61903921...
x
=
ln
(
11

)
≈
−
0.61903921...
Round result:
Round the result to the nearest hundredth.
