Question

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

Answer 1

Answer:

7x

Step-by-step explanation:

Assuming your expression is :

$e^{\ln 7x}$

Then we simplify as follows

$e^{\ln 7x}=e^{\ln x+\ln 7}$ since $\ln A+\ln B=\ln AB$

$\implies e^{\ln 7x}=e^{\ln x}\times e^{\ln 7}$ since $a^{m+n}=a^m\times a^n$

$\implies e^{\ln 7x}=x\times7$ since $e^{\ln a}=a$

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