$${ 2 }^{ x } =1024$$

Datrys ar gyfer x

$$x=10$$

Camau gan Ddefnyddio Diffiniad Logarithm

Defnyddio rheolau esbonyddion a logarithmau i ddatrys yr hafaliad.

$$2^{x}=1024$$

Cymryd logarithm dwy ochr yr hafaliad.

$$\log(2^{x})=\log(1024)$$

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

$$x\log(2)=\log(1024)$$

Rhannu’r ddwy ochr â \log(2).

$$x=\frac{\log(1024)}{\log(2)}$$

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

$$x=\log_{2}\left(1024\right)$$

Datrys ar gyfer x (complex solution)

$$x=\frac{2\pi n_{1}i}{\ln(2)}+10$$

$$n_{1}\in \mathrm{Z}$$
