Question

what is the value of e^In7x
a.1
b.7e
c.7x
d.7

Answer 1

I do believe the correct answer is 7x

Answer 2

Keywords:

Function, exponential, neperian logarithm, properties, argument of the function

For this case we have a function$f (x)$given by exponential and neperian logarithm, in which, by means of properties of exponential and neperian logarithm we must find the argument of the function. We have: $f (x) = e ^ {ln (7x)}$

By properties of exponential and neperian logarithm we have:

$e ^ {ln (x)} = x$

So, we have that:$f (x) = e ^ {ln (7x)} = 7x$

Then, the argument of the given function is: $7x$

Answer:

The value of $f (x) = e ^ {ln (7x)} is 7x$
