Question

Find p'(2) If p(x)=3^2x

Answer 1

replace x by 2 in the que....
so u will get 3^4
means 3*3*3*3
=81

Answer 2

Nooooooo. its wrong. there is a prime there!

Answer 3

prime there means

Answer 4

derivative!! @nirmalnema

Answer 5

p'(x) = 2*3^(2x).ln3
p'(2) = 2*3^(2*2).ln3=2*81*ln3=162.ln3

Answer 6

ohh..okk

Answer 7

Or p(x) = 9^x
p'(x) = 9^x*ln9 = 2*9^x*ln3
p'(2) = 2*9^2*ln3= 162*ln3 again if it is hard to derivate something^2x
