sqrt
→ sqrt()E busa modu wa sekwere wa palo — palo e fa e atisiwa ka boyona e busang palo e e neilweng.
sqrt(palo)sqrt(9) ke 3, ka gonne 3 × 3 ke 9. Ke yona sq e menotsweng.
Matswela ka metlha a kwa godimo ga 0. sqrt ga e dire ka dipalo tse di kwa tlase ga 0 — sqrt(-9) e busa NaN, e leng “e seng palo”.
Leina le sala jaaka le ntse, jaaka sq le pow. “Square root” ke mokwalo wa dipalo o moithuti wa Botswana a o kopanang le ona ka Seesemane mo tlelaseng — o tlhagelela mo dithutong tsa JCE le tsa BGCSE ka Seesemane fela; go le fetolela go ka mo naya lefoko le a se kang a le bona gope gape.
Mo mmetleng sqrt e dirisiwa go dira gore go gola go ritibale fa go tswelela — go simolola ka bonako mme go bo go iketla, e leng se se dirang gore motsamao o lebege o le tlhago.
