Solve 1.4^{2}+1.4^2+2.6^2+1.6^2+1.4^2

$$1.4 ^ { 2 } + 1.4 ^ { 2 } + 2.6 ^ { 2 } + 1.6 ^ { 2 } + 1.4 ^ { 2 }$$

Evaluate

$$15.2$$

Solution Steps

Calculate 1.4 to the power of 2 and get 1.96.

$$1.96+1.4^{2}+2.6^{2}+1.6^{2}+1.4^{2}$$

Calculate 1.4 to the power of 2 and get 1.96.

$$1.96+1.96+2.6^{2}+1.6^{2}+1.4^{2}$$

Add 1.96 and 1.96 to get 3.92.

$$3.92+2.6^{2}+1.6^{2}+1.4^{2}$$

Calculate 2.6 to the power of 2 and get 6.76.

$$3.92+6.76+1.6^{2}+1.4^{2}$$

Add 3.92 and 6.76 to get 10.68.

$$10.68+1.6^{2}+1.4^{2}$$

Calculate 1.6 to the power of 2 and get 2.56.

$$10.68+2.56+1.4^{2}$$

Add 10.68 and 2.56 to get 13.24.

$$13.24+1.4^{2}$$

Calculate 1.4 to the power of 2 and get 1.96.

$$13.24+1.96$$

Add 13.24 and 1.96 to get 15.2.

$$15.2$$

Factor

$$\frac{19 \cdot 2 ^ {2}}{5} = 15\frac{1}{5} = 15.2$$
