Solve 20.1*14quadtext{(4)}121*0.13+12.1*0.9-1.21*12

$$20.1 \times 14 \quad \text { (4) } 121 \times 0.13 + 12.1 \times 0.9 - 1.21 \times 12$$

Evaluate

$$17702.058$$

Solution Steps

Multiply 20.1 and 14 to get 281.4.

$$281.4\times 4\times 121\times 0.13+12.1\times 0.9-1.21\times 12$$

Multiply 281.4 and 4 to get 1125.6.

$$1125.6\times 121\times 0.13+12.1\times 0.9-1.21\times 12$$

Multiply 1125.6 and 121 to get 136197.6.

$$136197.6\times 0.13+12.1\times 0.9-1.21\times 12$$

Multiply 136197.6 and 0.13 to get 17705.688.

$$17705.688+12.1\times 0.9-1.21\times 12$$

Multiply 12.1 and 0.9 to get 10.89.

$$17705.688+10.89-1.21\times 12$$

Add 17705.688 and 10.89 to get 17716.578.

$$17716.578-1.21\times 12$$

Multiply 1.21 and 12 to get 14.52.

$$17716.578-14.52$$

Subtract 14.52 from 17716.578 to get 17702.058.

$$17702.058$$

Factor

$$\frac{3 \cdot 37 \cdot 659 \cdot 11 ^ {2}}{2 ^ {2} \cdot 5 ^ {3}} = 17702\frac{29}{500} = 17702.058$$
