Issolvi 8(2/3)^-1(6/4)(4/2)^-7

$$8 ( \frac { 2 } { 3 } ) ^ { - 1 } ( \frac { 6 } { 4 } ) ( \frac { 4 } { 2 } ) ^ { - 7 }$$

Evalwa

$$\frac{9}{64}=0.140625$$

Passi tas-Soluzzjonijiet

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

$$8\times \frac{3}{2}\times \frac{6}{4}\times \left(\frac{4}{2}\right)^{-7}$$

Immultiplika 8 u \frac{3}{2} biex tikseb 12.

$$12\times \frac{6}{4}\times \left(\frac{4}{2}\right)^{-7}$$

Naqqas il-frazzjoni \frac{6}{4} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 2.

$$12\times \frac{3}{2}\times \left(\frac{4}{2}\right)^{-7}$$

Immultiplika 12 u \frac{3}{2} biex tikseb 18.

$$18\times \left(\frac{4}{2}\right)^{-7}$$

Iddividi 4 b'2 biex tikseb2.

$$18\times 2^{-7}$$

Ikkalkula 2 bil-power ta' -7 u tikseb \frac{1}{128}.

$$18\times \frac{1}{128}$$

Immultiplika 18 u \frac{1}{128} biex tikseb \frac{9}{64}.

$$\frac{9}{64}$$

Fattur

$$\frac{3 ^ {2}}{2 ^ {6}} = 0.140625$$
