# CORE 3-Differentiation watch

1. Find the coordinates of the turning point on the curve

y=2e3x+8e-3x

and use d2y/dx2 to find the nature of the turning of the turning point.

I have differentiated and found dy/dx = 6e3x-24e-3x

At the turning point dy/dx will = 0 but how would I solve 6e3x-24e-3x​=0?

Hint:

Multiply through by e^3x and then it should be easy to solve!
