Camau gan Ddefnyddio Diffiniad Logarithm

Defnyddio rheolau esbonyddion a logarithmau i ddatrys yr hafaliad.

$$2^{n}=674$$

Cymryd logarithm dwy ochr yr hafaliad.

$$\log(2^{n})=\log(674)$$

Logarithm rhif wedi’i godi i bŵer yw’r pŵer wedi’i lluosi â logarithm y rhif.

$$n\log(2)=\log(674)$$

Rhannu’r ddwy ochr â \log(2).

$$n=\frac{\log(674)}{\log(2)}$$

Gyda’r fformiwla newid-sail \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).

$$n=\log_{2}\left(674\right)$$
