Solve 1+1.2^2+1.4^2+1.6^2+1.8^2

$$1+ { 1.2 }^{ 2 } + { 1.4 }^{ 2 } + { 1.6 }^{ 2 } + { 1.8 }^{ 2 }$$

Evaluate

$$10.2$$

Solution Steps

Calculate 1.2 to the power of 2 and get 1.44.

$$1+1.44+1.4^{2}+1.6^{2}+1.8^{2}$$

Add 1 and 1.44 to get 2.44.

$$2.44+1.4^{2}+1.6^{2}+1.8^{2}$$

Calculate 1.4 to the power of 2 and get 1.96.

$$2.44+1.96+1.6^{2}+1.8^{2}$$

Add 2.44 and 1.96 to get 4.4.

$$4.4+1.6^{2}+1.8^{2}$$

Calculate 1.6 to the power of 2 and get 2.56.

$$4.4+2.56+1.8^{2}$$

Add 4.4 and 2.56 to get 6.96.

$$6.96+1.8^{2}$$

Calculate 1.8 to the power of 2 and get 3.24.

$$6.96+3.24$$

Add 6.96 and 3.24 to get 10.2.

$$10.2$$

Factor

$$\frac{3 \cdot 17}{5} = 10\frac{1}{5} = 10.2$$
