Úprava výrazu
Uprav výraz:
\large \left[ \left( -x^{2} \right) ^{3} \right] ^{2}\cdot \left( -2 \right) ^{7}:x ^{3}\cdot y^{2}:2^{6}
\large = x ^{9} \cdot y^{3} \cdot \left( - 1 \right) \cdot 2^{1} =- 2 \cdot x ^{9} \cdot y^{3}
\large = x ^{9} \cdot y^{2} \cdot \left( - 1 \right) \cdot 2^{2} =- 4 \cdot x ^{9} \cdot y^{2}
\large = x ^{8} \cdot y^{2} \cdot \left( - 1 \right) \cdot 2^{1} =- 2 \cdot x ^{8} \cdot y^{2}
\large = x ^{9} \cdot y^{2} \cdot \left( - 1 \right) \cdot 2^{1} =- 2 \cdot x ^{9} \cdot y^{2}
Tady budeš počítat s neznámými, ale neboj, je to úplně stejné jako s čísly. Pro výpočet těchto příkladů si připomeneš, že plus krát plus dává plus, minus krát minus je plus a minus krát plus se rovná minus.
