Sa [[matematika]], an '''kwadradong gamot''' ([[Ingles]]: ''square root'') kan numerong {{math|''x''}} iyo an numerong {{math|''y''}} kun sain {{math|1=''y''<sup>2</sup> = ''x''}}; sa ibang pagsayod, an numerong {{math|''y''}} na an ''kwadrado'' (an resulta sa pagmultiplika kan numero sa saiyang sadiri, o {{math|''y''}} &#x22C5; {{math|''y''}}) iyo {{math|''x''}}.<ref>Gel'fand, [https://books.google.com/books?id=Z9z7iliyFD0C&pg=PA120 p. 120] {{webarchive|url=https://web.archive.org/web/20160902151740/https://books.google.com/books?id=Z9z7iliyFD0C&pg=PA120|date=2016-09-02}}

An lambang dae-negatibo na tunay na numerong {{math|''x''}} igwa nin unikong dae-negatibong kwadradong gamot, na inaapod na ''prinsipal na kwadradong gamot'', na pigsusurat na <math>\sqrt{x},</math><ref>{{Cite web|date=2020-03-01|title=Compendium of Mathematical Symbols|url=https://mathvault.ca/hub/higher-math/math-symbols/|access-date=2020-08-28|website=Math Vault|language=en-US}}</ref> kun sain an simbolong <math>\sqrt{~^~}</math> iyo inaapod na ''radikal na senyal''<ref>{{Cite web|title=Squares and Square Roots|url=https://www.mathsisfun.com/square-root.html|access-date=2020-08-28|website=www.mathsisfun.com}}</ref> o ''radix''. Halimbawa, an prinsipal na kwadradong gamot kan 9 iyo 3, na pigsusurat na <math>\sqrt{9} = 3,</math> huli ta an {{math|1=3<sup>2</sup> = 3 &sdot; 3 = 9}} asin an 3 iyo dae-negatibo. An termino (o numero) na an kwadradong gamot pigkokonsidera iyo bisto bilang an ''radicand''. An radicand iyo an numero o ekspresyon sa laog kan radikal na senyal, sa kasong ini iyo an 9.

An lambang positibong numerong {{math|''x''}} igwa nin duwang kwadradong gamot: <math>\sqrt{x},</math> na iyo positibo, asin <math>-\sqrt{x},</math> na iyo negatibo. Sa pagsalak, an duwang gamot iyo pigsusurat bilang <math>\plusmn\sqrt{x}</math>. Alagad an prinsipal na kwadradong gamot kan positibong numero iyo saro sana sa duwang kwadradong gamot kaini, an designasyon na "''an'' kwadradong gamot" iyo harus nagagamit dapit sa ''prinsipal na kwadradong gamot''. Para sa positibong {{math|''x''}}, an prinsipal na kwadradong gamot pwede man masurat sa [[Eksponentasyon|eksponentasyong]] notasyon, bilang {{math|''x''<sup>1/2</sup>}}.<ref>{{cite book|url=https://books.google.com/books?id=YKZqY8PCNo0C|title=A First Course in Complex Analysis With Applications|last1=Zill|first1=Dennis G.|last2=Shanahan|first2=Patrick|publisher=Jones & Bartlett Learning|year=2008|isbn=978-0-7637-5772-4|edition=2nd|page=78|archive-url=https://web.archive.org/web/20160901081936/https://books.google.com/books?id=YKZqY8PCNo0C|archive-date=2016-09-01|url-status=live}} [https://books.google.com/books?id=YKZqY8PCNo0C&pg=PA78 Extract of page 78] {{webarchive|url=https://web.archive.org/web/20160901091148/https://books.google.com/books?id=YKZqY8PCNo0C&pg=PA78|date=2016-09-01}}</ref><ref>{{Cite web|last=Weisstein|first=Eric W.|title=Square Root|url=https://mathworld.wolfram.com/SquareRoot.html|access-date=2020-08-28|website=mathworld.wolfram.com|language=en}}</ref>
