Evaluate

$$0.77525$$

Solution Steps

Multiply 0.65 and 0.7 to get 0.455.

$$0.455\times 0.25+0.35\times 0.7\times 0.75+0.65\times 0.3\times 0.7+0.34125$$

Multiply 0.455 and 0.25 to get 0.11375.

$$0.11375+0.35\times 0.7\times 0.75+0.65\times 0.3\times 0.7+0.34125$$

Multiply 0.35 and 0.7 to get 0.245.

$$0.11375+0.245\times 0.75+0.65\times 0.3\times 0.7+0.34125$$

Multiply 0.245 and 0.75 to get 0.18375.

$$0.11375+0.18375+0.65\times 0.3\times 0.7+0.34125$$

Add 0.11375 and 0.18375 to get 0.2975.

$$0.2975+0.65\times 0.3\times 0.7+0.34125$$

Multiply 0.65 and 0.3 to get 0.195.

$$0.2975+0.195\times 0.7+0.34125$$

Multiply 0.195 and 0.7 to get 0.1365.

$$0.2975+0.1365+0.34125$$

Add 0.2975 and 0.1365 to get 0.434.

$$0.434+0.34125$$

Add 0.434 and 0.34125 to get 0.77525.

$$0.77525$$

Factor

$$\frac{7 \cdot 443}{2 ^ {5} \cdot 5 ^ {3}} = 0.77525$$
