Malunga nale khadi

A square root calculator gives the principal (positive) square root of a number, plus its simplified radical form and whether the number is a perfect square. Enter any non-negative number to see both the decimal value and the exact radical.

The simplified radical is found by pulling the largest perfect-square factor outside the root sign. For √72, the largest perfect square dividing 72 is 36, so √72 = √(36 × 2) = 6√2 — an exact form, unlike the rounded decimal 8.485. When the number is itself a perfect square, such as 36, the root is a whole number (6) and the tool flags it as a perfect square.

Square roots appear in the Pythagorean theorem, the distance formula, standard deviation and quadratic equations. Note that every positive number has two square roots, one positive and one negative; this tool returns the principal positive root, and negative inputs have no real square root.

Imibuzo ebuzwa kaningi

Yini i-radical elula?

Ibhala kabusha umfundaze ngokuhlukanisa isikwere esiphelele esikhulu. √72 = √(36×2) = 6√2, okuyiqiniso, kungafani nenani elilinganayo leshumi elijikelezayo 8.485.

Ingabe isiqephu seroot senombolo sihlala si positive?

Inani ngalinye eliphumelelayo linezinkolelo ezimbili ezisikwele, eyodwa ephumelelayo nenye elahlekile. Lezi zinto zibuyisela inkolelo eyinhloko (ephumelelayo), eyisiphetho esijwayelekile se-√.

Yini isisu esisodwa se-72?

Ilingana no-8.485, futhi indlela yayo elula ilingana no-6√2.

Yini isikwere esiphelele?

Inani eliphelele elinoku-square root eliyisi-8 futhi liyinani eliphelele, njenge-36 (√36 = 6). Ithuluzi litshela ukuthi ngabe inani lakho lifaneleka.

Ingabe ngizothatha isiqephu seroot senombolo e negativ?

Ayikho ngaphakathi kwamanani angempela — ama-inputs a negative angeke abe ne-square root angempela. Uzodinga ama-numbers anzima, lapho √−4 = 2i.

Kungani ubonisa i-radical elula endaweni ye-decimal?

Ifomu le-radical lilungile. 6√2 lilungile, kanti 8.485 liyisimo esijikelezayo esilahla ukuthembeka emikhankasweni eminingi.
