Datrys 9*10^9*4*10^-6*6*10^-9

$$9 \times { 10 }^{ 9 } \times 4 \times { 10 }^{ -6 } \times 6 \times { 10 }^{ -9 }$$

Enrhifo

$$\frac{27}{125000}=0.000216$$

Camau Ateb

Er mwyn lluosi pwerau sy’n rhannu’r un sail, adiwch eu esbonyddion. Adiwch 9 a -6 i gael 3.

$$9\times 10^{3}\times 4\times 6\times 10^{-9}$$

Er mwyn lluosi pwerau sy’n rhannu’r un sail, adiwch eu esbonyddion. Adiwch 3 a -9 i gael -6.

$$9\times 10^{-6}\times 4\times 6$$

Cyfrifo 10 i bŵer -6 a chael \frac{1}{1000000}.

$$9\times \frac{1}{1000000}\times 4\times 6$$

Lluosi 9 a \frac{1}{1000000} i gael \frac{9}{1000000}.

$$\frac{9}{1000000}\times 4\times 6$$

Lluosi \frac{9}{1000000} a 4 i gael \frac{9}{250000}.

$$\frac{9}{250000}\times 6$$

Lluosi \frac{9}{250000} a 6 i gael \frac{27}{125000}.

$$\frac{27}{125000}$$

Ffactor

$$\frac{3 ^ {3}}{2 ^ {3} \cdot 5 ^ {6}} = 0.000216$$
