Given:

The equation is:

270=3e^{2.4K}

To find:

The solution for the given equation to the nearest hundredth.

Solution:

We have,

270=3e^{2.4K}

Divide both sides by 3.

\dfrac{270}{3}=e^{2.4K}

90=e^{2.4K}

Taking ln on both sides, we get

\ln (90)=\ln e^{2.4K}

\ln (90)=2.4K                  [\because \ln e^x=x]

Divide both sides by 2.4.

\dfrac{\ln (90)}{2.4}=K

\dfrac{4.4998}{2.4}=K           [\because \ln (90)\approx 4.4998]

1.874916667=K

Round the value to the nearest hundredth (two decimal place)

K\approx 1.87

Therefore, the value of K is 1.87.
