Whakaoti i te 5=(1.6*10^-4)(1+A)

$$5 = ( 1.6 \cdot 10 ^ { - 4 } ) ( 1 + A )$$

Whakaoti mō A

$$A=31249$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tātaihia te 10 mā te pū o -4, kia riro ko \frac{1}{10000}.

$$5=1.6\times \frac{1}{10000}\left(1+A\right)$$

Whakareatia te 1.6 ki te \frac{1}{10000}, ka \frac{1}{6250}.

$$5=\frac{1}{6250}\left(1+A\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te \frac{1}{6250} ki te 1+A.

$$5=\frac{1}{6250}+\frac{1}{6250}A$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$\frac{1}{6250}+\frac{1}{6250}A=5$$

Tangohia te \frac{1}{6250} mai i ngā taha e rua.

$$\frac{1}{6250}A=5-\frac{1}{6250}$$

Tangohia te \frac{1}{6250} i te 5, ka \frac{31249}{6250}.

$$\frac{1}{6250}A=\frac{31249}{6250}$$

Me whakarea ngā taha e rua ki te 6250, te tau utu o \frac{1}{6250}.

$$A=\frac{31249}{6250}\times 6250$$

Whakareatia te \frac{31249}{6250} ki te 6250, ka 31249.

$$A=31249$$
