Ako vypocitam polozku "10 na nazov_stlpec" v SELEC

Mam taky problem. Potrebujem vypocitat hodnotu type kde potrebujem pouzit funkciu 10 na nieco. Tu je ten dotaz:

SELECT A.aid AS aid, N.nazov AS nazov, N.kedy AS kedy, SUM((10 na (G.glow + 1))*gtype) AS type
FROM action A JOIN action_name N JOIN galery G ON A.aid = N.aid AND A.aid = G.aid
WHERE N.lan = '$lan' AND G.glow <= $low
GROUP BY A.aid
ORDER BY A.datum DESC;

Nepoznate daku funkciu v MySQL na vypocet 10_na_nieco?
