Evaluate in 7<br> 0.51<br> 1.95<br> 0.85<br> 1.61
Ber [7]

Answer:

We may log in directly in our scientific calculator the given value ln 7 and get an answer of 1.9459. On the other hand, we can rewrite the expression as,

                            log to the base e or 7 = x

which can be written as,

                              e^x = 7

The value of x from this is still equal to 1.9459.
