Datrys 1/1728*(1/a^12)-(1/b^6)

$$\frac { 1 } { 1728 } \cdot ( \frac { 1 } { a ^ { 12 } } ) - ( \frac { 1 } { b ^ { 6 } } )$$

Enrhifo

$$-\frac{1}{b^{6}}+\frac{1}{1728a^{12}}$$

Camau Ateb Byr

Lluoswch \frac{1}{1728} â \frac{1}{a^{12}} drwy luosi'r rhifiadur â’r rhifiadur a'r enwadur â’r enwadur.

$$\frac{1}{1728a^{12}}-\frac{1}{b^{6}}$$

I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin 1728a^{12} a b^{6} yw 1728b^{6}a^{12}. Lluoswch \frac{1}{1728a^{12}} â \frac{b^{6}}{b^{6}}. Lluoswch \frac{1}{b^{6}} â \frac{1728a^{12}}{1728a^{12}}.

$$\frac{b^{6}}{1728b^{6}a^{12}}-\frac{1728a^{12}}{1728b^{6}a^{12}}$$

Gan fod gan \frac{b^{6}}{1728b^{6}a^{12}} a \frac{1728a^{12}}{1728b^{6}a^{12}} yr un dynodydd, tynnwch nhw drwy dynnu eu rhifiaduron.

$$\frac{b^{6}-1728a^{12}}{1728b^{6}a^{12}}$$

Ffactor

$$\frac{-1728+\frac{b^{6}}{a^{12}}}{1728b^{6}}$$
