$$\frac{ x-1 }{ \frac{ 5 }{ { \left( \frac{ x }{ 5 } \right) }^{ 3 } - \frac{ 1 }{ 5 } } }$$

Evalwa

$$\frac{\left(x-1\right)\left(x^{3}-25\right)}{625}$$

Passi tas-Soluzzjonijiet

Iddividi x-1 b'\frac{5}{\left(\frac{x}{5}\right)^{3}-\frac{1}{5}} billi timmultiplika x-1 bir-reċiproku ta' \frac{5}{\left(\frac{x}{5}\right)^{3}-\frac{1}{5}}.

$$\frac{\left(x-1\right)\left(\left(\frac{x}{5}\right)^{3}-\frac{1}{5}\right)}{5}$$

Biex tgħolli \frac{x}{5} għal qawwa, għolli kemm in-numeratur u d-denominatur għall-qawwa u mbagħad iddividi.

$$\frac{\left(x-1\right)\left(\frac{x^{3}}{5^{3}}-\frac{1}{5}\right)}{5}$$

Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. L-inqas multiplu komuni ta' 5^{3} u 5 huwa 125. Immultiplika \frac{1}{5} b'\frac{25}{25}.

$$\frac{\left(x-1\right)\left(\frac{x^{3}}{125}-\frac{25}{125}\right)}{5}$$

Billi \frac{x^{3}}{125} u \frac{25}{125} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{\left(x-1\right)\times \frac{x^{3}-25}{125}}{5}$$

Esprimi \left(x-1\right)\times \frac{x^{3}-25}{125} bħala frazzjoni waħda.

$$\frac{\frac{\left(x-1\right)\left(x^{3}-25\right)}{125}}{5}$$

Esprimi \frac{\frac{\left(x-1\right)\left(x^{3}-25\right)}{125}}{5} bħala frazzjoni waħda.

$$\frac{\left(x-1\right)\left(x^{3}-25\right)}{125\times 5}$$

Immultiplika 125 u 5 biex tikseb 625.

$$\frac{\left(x-1\right)\left(x^{3}-25\right)}{625}$$

Uża l-propjetà distributtiva biex timmultiplika x-1 b'x^{3}-25.

$$\frac{x^{4}-25x-x^{3}+25}{625}$$

Espandi

$$\frac{x^{4}}{625}-\frac{x^{3}}{625}-\frac{x}{25}+\frac{1}{25}$$
