Answer:
x=3 , x=-3
Step-by-step explanation:
[tex]e^{lnx^2} -9= 0[/tex]
Add 9 on both sides
[tex]e^{lnx^2}=9[/tex]
To remove base 'e' we take ln on both sides
[tex]ln e^{lnx^2}=ln9[/tex]
[tex]lnx^2=ln(9)[/tex]
Both sides have ln , so we make the terms equal
[tex]x^2=9[/tex]
Take square root on both sides
[tex]x=+-3[/tex]
x=3 , x=-3
