[tex]x = \frac{7}{9} [/tex]
Step-by-step explanation:
[tex]9x = 7 \\ \frac{9x}{9} = \frac{7}{9} \\ x = \frac{7}{9} [/tex]
Answer:
[tex]x=0.885622[/tex]
Step-by-step explanation:
Given that an exponential equation in x as
[tex]9^x + 4 = 11[/tex]
We have to solve for x using change of base formula for log
Subtract 4 from both the sides
[tex]9^x =7[/tex]
Take log to base 9
[tex]x=log_9 7[/tex]
Using change of base to 10 we have
[tex]x=\frac{log 7}{log 9}[/tex] taking same to base 10 by using change of base formula
[tex]x=0.885622[/tex]
