Can someone explain to me why e^ln 7 is equal to 7? ...?

1 answer:

7 0

There is a law in logarithm and exponentials where b^log_b(x) = x. Well, ln(x) = log_e(x). Then, rewriting the equation

e^ln(7)
= e^log_e(7). Applying the law,
= 7

A precise paragraph is the gist of the whole content. I had surprised myself by being able to do the thing is the sentence that can replace the fifth sentence.

<h3>What is precise writing?</h3>

Precise writing is compression or the gist writing of the content highlighting just the important words. It covers the key details from the original text and explains them precisely.

It uses few words from the original text and conveys the idea to the readers. The fifth sentence can be replaced by using the words surprised, able, and myself.

Therefore, the fifth sentence can be replaced by option C. I had surprised myself.
