Solve 10^3*9.8*120*10^-3-10^3*9.8*200*10^-3-920*9.8*120*{10}^-3

$${ 10 }^{ 3 } \times 9.8 \times 120 \times { 10 }^{ -3 } - { 10 }^{ 3 } \times 9.8 \times 200 \times { 10 }^{ -3 } -920 \times 9.8 \times 120 \times { 10 }^{ -3 }$$

Evaluate

$$-1865.92$$

Solution Steps

Multiply 10^{3} and 10^{-3} to get 1.

$$9.8\times 120-10^{3}\times 9.8\times 200\times 10^{-3}-920\times 9.8\times 120\times 10^{-3}$$

Multiply 10^{3} and 10^{-3} to get 1.

$$9.8\times 120-9.8\times 200-920\times 9.8\times 120\times 10^{-3}$$

Multiply 9.8 and 120 to get 1176.

$$1176-9.8\times 200-920\times 9.8\times 120\times 10^{-3}$$

Multiply 9.8 and 200 to get 1960.

$$1176-1960-920\times 9.8\times 120\times 10^{-3}$$

Subtract 1960 from 1176 to get -784.

$$-784-920\times 9.8\times 120\times 10^{-3}$$

Multiply 920 and 9.8 to get 9016.

$$-784-9016\times 120\times 10^{-3}$$

Multiply 9016 and 120 to get 1081920.

$$-784-1081920\times 10^{-3}$$

Calculate 10 to the power of -3 and get \frac{1}{1000}.

$$-784-1081920\times \frac{1}{1000}$$

Multiply 1081920 and \frac{1}{1000} to get \frac{27048}{25}.

$$-784-\frac{27048}{25}$$

Subtract \frac{27048}{25} from -784 to get -\frac{46648}{25}.

$$-\frac{46648}{25}$$

Factor

$$-1865.92$$
