#2) Use quotient rule
Remember for solving log equations:
#3) Derivative of tan = sec^2 = 1/cos^2
Domain of tan is [-pi/2, pi/2], only consider x values in that domain.
#4 Use Quotient rule
#9 Use double angle identity for tan
This way you can rewrite tan(pi/2) in terms of tan(pi/4).
Next use L'hopitals rule, which says the limit of indeterminate form(0/0) equals limit of quotient of derivatives of top/bottom of fraction.
Take derivative of both top part and bottom part separately, then reevaluate the limit. <span />

Answer:
A
Step-by-step explanation:
Remember that x^(b-c)
Using that =3^(1/2x-1/2)=3^((x-1)/2)
So we can say: , because the bases are the same
We can multiply both sides of the equation by 2. We get x-1=2, and x=3. Which is A.
