Answer:
7x
Step-by-step explanation:
Assuming your expression is :
[tex]e^{\ln 7x}[/tex]
Then we simplify as follows
[tex]e^{\ln 7x}=e^{\ln x+\ln 7}[/tex] since [tex]\ln A+\ln B=\ln AB[/tex]
[tex]\implies e^{\ln 7x}=e^{\ln x}\times e^{\ln 7}[/tex] since [tex]a^{m+n}=a^m\times a^n[/tex]
[tex]\implies e^{\ln 7x}=x\times7[/tex] since [tex]e^{\ln a}=a[/tex]
[tex]\implies e^{\ln 7x}=7x[/tex]
