Hi
Can somebody explain the change (in words) of how the upper part becomes the lower part?
Thanks
Dear 200001,
You can take the reciprocal of both sides. Then $\displaystyle \frac{1}{8\sqrt{x}}$ becomes $\displaystyle 8\sqrt{x}$ and $\displaystyle e^{1-4x}$ becomes $\displaystyle e^{-(1-4x)}=e^{4x-1}$
