Solve 31.8^2-2*31.8*21.8*21.8^2

$${ 31.8 }^{ 2 } -2 \times 31.8 \times 21.8 \times { 21.8 }^{ 2 }$$

Evaluate

$$-657899.5152$$

Solution Steps

To multiply powers of the same base, add their exponents. Add 1 and 2 to get 3.

$$31.8^{2}-2\times 31.8\times 21.8^{3}$$

Calculate 31.8 to the power of 2 and get 1011.24.

$$1011.24-2\times 31.8\times 21.8^{3}$$

Multiply 2 and 31.8 to get 63.6.

$$1011.24-63.6\times 21.8^{3}$$

Calculate 21.8 to the power of 3 and get 10360.232.

$$1011.24-63.6\times 10360.232$$

Multiply 63.6 and 10360.232 to get 658910.7552.

$$1011.24-658910.7552$$

Subtract 658910.7552 from 1011.24 to get -657899.5152.
