Solve 140*1.9-481.9^2+41.9^3

$$140 \cdot 1.9-48 { 1.9 }^{ 2 } +4 { 1.9 }^{ 3 }$$

Evaluate

$$120.156$$

Solution Steps

Multiply 140 and 1.9 to get 266.

$$266-48\times 1.9^{2}+4\times 1.9^{3}$$

Calculate 1.9 to the power of 2 and get 3.61.

$$266-48\times 3.61+4\times 1.9^{3}$$

Multiply 48 and 3.61 to get 173.28.

$$266-173.28+4\times 1.9^{3}$$

Subtract 173.28 from 266 to get 92.72.

$$92.72+4\times 1.9^{3}$$

Calculate 1.9 to the power of 3 and get 6.859.

$$92.72+4\times 6.859$$

Multiply 4 and 6.859 to get 27.436.

$$92.72+27.436$$

Add 92.72 and 27.436 to get 120.156.

$$120.156$$

Factor

$$\frac{3 \cdot 17 \cdot 19 \cdot 31}{2 \cdot 5 ^ {3}} = 120\frac{39}{250} = 120.156$$
