Datrys ar gyfer k
k=m+\left(\frac{n}{m}\right)^{2}
\left(m>0\text{ and }n>0\right)\text{ or }\left(m<0\text{ and }n<0\right)
Rhannu
Copïo i clipfwrdd
\frac{\frac{1}{n}\sqrt{k-m}n}{1}=\frac{1}{m\times \frac{1}{n}}
Rhannu’r ddwy ochr â n^{-1}.
\sqrt{k-m}=\frac{1}{m\times \frac{1}{n}}
Mae rhannu â n^{-1} yn dad-wneud lluosi â n^{-1}.
\sqrt{k-m}=\frac{n}{m}
Rhannwch \frac{1}{m} â n^{-1}.
k-m=\frac{n^{2}}{m^{2}}
Sgwariwch ddwy ochr yr hafaliad.
k-m-\left(-m\right)=\frac{n^{2}}{m^{2}}-\left(-m\right)
Tynnu -m o ddwy ochr yr hafaliad.
k=\frac{n^{2}}{m^{2}}-\left(-m\right)
Mae tynnu -m o’i hun yn gadael 0.
k=m+\frac{n^{2}}{m^{2}}
Tynnu -m o \frac{n^{2}}{m^{2}}.
