Whakaoti mō f
f=y\times 2^{x}
y\neq 0
Whakaoti mō x (complex solution)
x=\frac{2\pi n_{1}i}{\ln(2)}+\log_{2}\left(\frac{f}{y}\right)
n_{1}\in \mathrm{Z}
f\neq 0\text{ and }y\neq 0
Whakaoti mō x
x=\log_{2}\left(\frac{f}{y}\right)
\left(f<0\text{ and }y<0\right)\text{ or }\left(f>0\text{ and }y>0\right)

Kua tāruatia ki te papatopenga
\frac{1}{y}f=2^{x}
He hanga arowhānui tō te whārite.
\frac{\frac{1}{y}fy}{1}=\frac{2^{x}y}{1}
Whakawehea ngā taha e rua ki te y^{-1}.
f=\frac{2^{x}y}{1}
Mā te whakawehe ki te y^{-1} ka wetekia te whakareanga ki te y^{-1}.
f=y\times 2^{x}
Whakawehe 2^{x} ki te y^{-1}.
