9-\sqrt{0.25}+\sqrt{\frac{9}{4}}

Ikkalkula l-għerq kwadrat ta' 81 u ikseb 9.

9-0.5+\sqrt{\frac{9}{4}}

Ikkalkula l-għerq kwadrat ta' 0.25 u ikseb 0.5.

8.5+\sqrt{\frac{9}{4}}

Naqqas 0.5 minn 9 biex tikseb 8.5.

8.5+\frac{3}{2}

Erġa' ikteb id-diviżjoni tal-għerq kwadrat \frac{9}{4} bħala d-diviżjoni tal-għeruq kwadrati \frac{\sqrt{9}}{\sqrt{4}}. Ħu r-radiċi kwadrata tan-numeratur u d-denominatur.

\frac{17}{2}+\frac{3}{2}

Ikkonverti n-numru deċimali 8.5 fi frazzjoni \frac{85}{10}. Naqqas il-frazzjoni \frac{85}{10} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 5.

\frac{17+3}{2}

Billi \frac{17}{2} u \frac{3}{2} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

\frac{20}{2}

Żid 17 u 3 biex tikseb 20.

Iddividi 20 b'2 biex tikseb10.
