Passi tas-Soluzzjonijiet

Ikkalkula 3 bil-power ta' 2 u tikseb 9.

$$\frac{-9\times 1.2^{2}}{\left(-0.3\right)^{3}}+\frac{\left(-\frac{1}{3}\right)^{2}\left(-3\right)^{3}}{\left(-1\right)^{25}}$$

Ikkalkula 1.2 bil-power ta' 2 u tikseb 1.44.

$$\frac{-9\times 1.44}{\left(-0.3\right)^{3}}+\frac{\left(-\frac{1}{3}\right)^{2}\left(-3\right)^{3}}{\left(-1\right)^{25}}$$

Immultiplika -9 u 1.44 biex tikseb -12.96.

$$\frac{-12.96}{\left(-0.3\right)^{3}}+\frac{\left(-\frac{1}{3}\right)^{2}\left(-3\right)^{3}}{\left(-1\right)^{25}}$$

Ikkalkula -0.3 bil-power ta' 3 u tikseb -0.027.

$$\frac{-12.96}{-0.027}+\frac{\left(-\frac{1}{3}\right)^{2}\left(-3\right)^{3}}{\left(-1\right)^{25}}$$

Espandi \frac{-12.96}{-0.027} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'1000.

$$\frac{-12960}{-27}+\frac{\left(-\frac{1}{3}\right)^{2}\left(-3\right)^{3}}{\left(-1\right)^{25}}$$

Iddividi -12960 b'-27 biex tikseb480.

$$480+\frac{\left(-\frac{1}{3}\right)^{2}\left(-3\right)^{3}}{\left(-1\right)^{25}}$$

Ikkalkula -\frac{1}{3} bil-power ta' 2 u tikseb \frac{1}{9}.

$$480+\frac{\frac{1}{9}\left(-3\right)^{3}}{\left(-1\right)^{25}}$$

Ikkalkula -3 bil-power ta' 3 u tikseb -27.

$$480+\frac{\frac{1}{9}\left(-27\right)}{\left(-1\right)^{25}}$$

Immultiplika \frac{1}{9} u -27 biex tikseb \frac{-27}{9}.

$$480+\frac{\frac{-27}{9}}{\left(-1\right)^{25}}$$

Iddividi -27 b'9 biex tikseb-3.

$$480+\frac{-3}{\left(-1\right)^{25}}$$

Ikkalkula -1 bil-power ta' 25 u tikseb -1.

$$480+\frac{-3}{-1}$$

Frazzjoni \frac{-3}{-1} tista' tiġi ssimplifikata għal 3 bit-tneħħija tas-sinjal negattiv min-numeratur u d-denominatur.

$$480+3$$

Żid 480 u 3 biex tikseb 483.
