**Reiny**, Monday, April 19, 2010 at 9:34pmfirst the easy part,

when x = 1/2 y = 8^(1/2) = √8

so our point is (1/2, √8)

I will take ln of both sides

ln y = ln 8^x

lny = x(ln8)

(dy/dx) / y = ln8

dy/dx = ln8(8^x)

so at (1/2, √8)

dy/dx = (ln8)(√8)

so you have m = ln8(√8) and the point (1/2, √8)

find the equation of the line.
