As long as your walkway isn't cracked all the way through, you can coat the slab with a concrete resurfacer, a no-shrink blend of Portland cement, sand, and polymer additives that fills divots and makes a uniform finish. Its natural color is dark gray, so buy enough to cover your entire walk. One 40-pound bag coats about 35 square feet. If you want a different color, just add a concrete tint. Before resurfacing, strip off any paint or sealers and watch the weather. Temperatures should remain above 50 degrees F for 8 hours after the pour and above freezing for 24 hours after that.
To do this, click the little down arrow that is located to the right of the text color command. If you float your curser over it, it will say More Buttons, and then click Add or Remove Buttons.

Click on the square next to the subscript and/or superscript. Once that is done you can click ok/accept and your font is superscript/subscript. Here is how you do it again.
