6^{2p}=216
Defnyddio rheolau esbonyddion a logarithmau i ddatrys yr hafaliad.
\log(6^{2p})=\log(216)
Cymryd logarithm dwy ochr yr hafaliad.
2p\log(6)=\log(216)
Logarithm rhif wedi’i godi i bŵer yw’r pŵer wedi’i lluosi â logarithm y rhif.
2p=\frac{\log(216)}{\log(6)}
Rhannu’r ddwy ochr â \log(6).
2p=\log_{6}\left(216\right)
Gyda’r fformiwla newid-sail \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).
p=\frac{3}{2}
Rhannu’r ddwy ochr â 2.
