Momba ity kapila ity
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.
Fanontaniana matetika
Inona no atao hoe radika tsotra?
It rewrites a root by factoring out the largest perfect square. √72 = √(36×2) = 6√2, which is exact, unlike the rounded decimal 8.485.
Ny fahazakan'ny isa dia ny fahazakan'ny isa miisa isaky ny isa.
Manana faka efatra roa ny isa rehetra, iray miabo ary iray ratsy. Mamaly ny faka voalohany (miabo) ity fitaovana ity, izay ny vokatry ny √ mahazatra.
Inona no fototra efatra amin'ny 72?
It is about 8.485, and its exact simplified form is 6√2.
Inona no atao hoe "karazana"?
Isa feno izay isa feno ihany koa ny fakany, toy ny 36 (√36 = 6). Milaza anao ny fitaovana raha mifanaraka amin'izany ny isao.
Azoko atao ve ny maka ny faka karetsaka amin'ny isa negatify?
Tsy ao anatin'ny isa tena izy — tsy manana fototra efatra tena izy ny fandefasana negatifa. Mila isa mitambatra ianao, izay √−4 = 2i.
Nahoana no asehon'ny rafitra ny radika tsotra fa tsy ny isa decimal?
The radical form is exact. 6√2 is precise, while 8.485 is a rounded approximation that loses accuracy in further calculations.
