Solve 38.9^2-2*38.9*48.9+48.9^2

$${ 38.9 }^{ 2 } -2 \times 38.9 \times 48.9+ { 48.9 }^{ 2 }$$

Evaluate

$$100$$

Solution Steps

Calculate 38.9 to the power of 2 and get 1513.21.

$$1513.21-2\times 38.9\times 48.9+48.9^{2}$$

Multiply 2 and 38.9 to get 77.8.

$$1513.21-77.8\times 48.9+48.9^{2}$$

Multiply 77.8 and 48.9 to get 3804.42.

$$1513.21-3804.42+48.9^{2}$$

Subtract 3804.42 from 1513.21 to get -2291.21.

$$-2291.21+48.9^{2}$$

Calculate 48.9 to the power of 2 and get 2391.21.

$$-2291.21+2391.21$$

Add -2291.21 and 2391.21 to get 100.

$$100$$

Factor

$$2^{2}\times 5^{2}$$
