Datrys (1+t^2)^3

$$( 1 + t ^ { 2 } ) ^ { 3 }$$

Enrhifo

$$\left(t^{2}+1\right)^{3}$$

Camau Ateb

Defnyddio'r theorem binomaidd \left(a+b\right)^{3}=a^{3}+3a^{2}b+3ab^{2}+b^{3} i ehangu'r \left(1+t^{2}\right)^{3}.

$$1+3t^{2}+3\left(t^{2}\right)^{2}+\left(t^{2}\right)^{3}$$

I godi pŵer rhif i bŵer arall, lluoswch yr esbonyddion. Lluoswch 2 a 2 i gael 4.

$$1+3t^{2}+3t^{4}+\left(t^{2}\right)^{3}$$

I godi pŵer rhif i bŵer arall, lluoswch yr esbonyddion. Lluoswch 2 a 3 i gael 6.

$$1+3t^{2}+3t^{4}+t^{6}$$

Ehangu

$$t^{6}+3t^{4}+3t^{2}+1$$
