Solve 11.9^2+10.8^2-2(11.9)(10.8)

$${ 11.9 }^{ 2 } + { 10.8 }^{ 2 } -2(11.9)(10.8)$$

Evaluate

$$1.21$$

Solution Steps

Calculate 11.9 to the power of 2 and get 141.61.

$$141.61+10.8^{2}-2\times 11.9\times 10.8$$

Calculate 10.8 to the power of 2 and get 116.64.

$$141.61+116.64-2\times 11.9\times 10.8$$

Add 141.61 and 116.64 to get 258.25.

$$258.25-2\times 11.9\times 10.8$$

Multiply 2 and 11.9 to get 23.8.

$$258.25-23.8\times 10.8$$

Multiply 23.8 and 10.8 to get 257.04.

$$258.25-257.04$$

Subtract 257.04 from 258.25 to get 1.21.

$$1.21$$

Factor

$$\frac{11 ^ {2}}{2 ^ {2} \cdot 5 ^ {2}} = 1\frac{21}{100} = 1.21$$
