Pasos da solución

Para multiplicar potencias da mesma base, suma os seus expoñentes. Suma 2 e 1 para obter 3.

$$1.3^{2}\times 0.3^{2}+0.3^{3}+\left(2-1.3\right)^{2}\times 0.2+1.7^{2}\times 0.2$$

Calcula 1.3 á potencia de 2 e obtén 1.69.

$$1.69\times 0.3^{2}+0.3^{3}+\left(2-1.3\right)^{2}\times 0.2+1.7^{2}\times 0.2$$

Calcula 0.3 á potencia de 2 e obtén 0.09.

$$1.69\times 0.09+0.3^{3}+\left(2-1.3\right)^{2}\times 0.2+1.7^{2}\times 0.2$$

Multiplica 1.69 e 0.09 para obter 0.1521.

$$0.1521+0.3^{3}+\left(2-1.3\right)^{2}\times 0.2+1.7^{2}\times 0.2$$

Calcula 0.3 á potencia de 3 e obtén 0.027.

$$0.1521+0.027+\left(2-1.3\right)^{2}\times 0.2+1.7^{2}\times 0.2$$

Suma 0.1521 e 0.027 para obter 0.1791.

$$0.1791+\left(2-1.3\right)^{2}\times 0.2+1.7^{2}\times 0.2$$

Resta 1.3 de 2 para obter 0.7.

$$0.1791+0.7^{2}\times 0.2+1.7^{2}\times 0.2$$

Calcula 0.7 á potencia de 2 e obtén 0.49.

$$0.1791+0.49\times 0.2+1.7^{2}\times 0.2$$

Multiplica 0.49 e 0.2 para obter 0.098.

$$0.1791+0.098+1.7^{2}\times 0.2$$

Suma 0.1791 e 0.098 para obter 0.2771.

$$0.2771+1.7^{2}\times 0.2$$

Calcula 1.7 á potencia de 2 e obtén 2.89.

$$0.2771+2.89\times 0.2$$

Multiplica 2.89 e 0.2 para obter 0.578.

$$0.2771+0.578$$

Suma 0.2771 e 0.578 para obter 0.8551.

$$0.8551$$
