Solve 2.1^2+2.2^2+23^2+2.4^2=

$$2.1 ^ { 2 } + 2.2 ^ { 2 } + 23 ^ { 2 } + 2.4 ^ { 2 } =$$

Evaluate

$$544.01$$

Solution Steps

Calculate 2.1 to the power of 2 and get 4.41.

$$4.41+2.2^{2}+23^{2}+2.4^{2}$$

Calculate 2.2 to the power of 2 and get 4.84.

$$4.41+4.84+23^{2}+2.4^{2}$$

Add 4.41 and 4.84 to get 9.25.

$$9.25+23^{2}+2.4^{2}$$

Calculate 23 to the power of 2 and get 529.

$$9.25+529+2.4^{2}$$

Add 9.25 and 529 to get 538.25.

$$538.25+2.4^{2}$$

Calculate 2.4 to the power of 2 and get 5.76.

$$538.25+5.76$$

Add 538.25 and 5.76 to get 544.01.

$$544.01$$

Factor

$$\frac{54401}{2 ^ {2} \cdot 5 ^ {2}} = 544\frac{1}{100} = 544.01$$
