#### To determine

**To find:**

We have to find the values of eln300 and ln(e300).

#### Answer

the values of eln300 and ln(e300) is 300.

#### Explanation

**Calculation:**

**(a)**

We have to find the value of eln300.

Since

elnx=x

So

eln300=300

Next, we find the value of ln(e300).

Since

lnex=x

So

ln(e300)=300

**(b)**

Now, we find the value of eln300 by using scientific calculator.

By using scientific calculator ln300≈5.70 and e5.70≈300.

Now, we find the value of ln(e300) by using scientific calculator.

By using scientific calculator e300 is a very large number and calculator can not find these types of large numbers.

**Final statement:** the values of eln300 and ln(e300) is 300.
