To convert the dimensions from meters to millimeters, we need to multiply them by 1000 since 1 meter is equal to 1000 millimeters.

The width of the sticky note is 1.25 x 10^-8 meters. Multiplying this by 1000, we get:
1.25 x 10^-8 m * 1000 = 1.25 x 10^-5 millimeters

The length of the sticky note is 2.5 x 10^-6 meters. Multiplying this by 1000, we get:
2.5 x 10^-6 m * 1000 = 2.5 x 10^-3 millimeters

Therefore, the dimensions of the sticky note in millimeters are 1.25 x 10^-5 by 2.5 x 10^-3.

The correct answer is:
1.25 x 10^-5 by 2.5 x 10^-3 millimeters.
