Question

What is the value of e^ln7 x1 7e 7x 7

Answer 1

Answer:

Both answer shown

IF it is

$e^{ln 7x}= 7x$

OR

IF it is

$e^{ln 7}\times 1}=7$

Step-by-step explanation:

Given: Little confusion is in the question

e^ln7 x1

i.e $e^{ln 7x}$

To Find:

$e^{ln 7x}= ?$

Solution:

We know Logarithmic identity as

1. $\ln e = 1$

2. $\ln e^{x} = x$

Similarly,

3. $e^{\ln x}=x$

IF it is

$e^{ln 7x}= 7x$

OR

IF it is

$e^{ln 7}\times 1}=7\times 1=7$
