Solve 5^2+3^2+7^2/2(7*5)=

$$\frac{ { 5 }^{ 2 } + { 3 }^{ 2 } + { 7 }^{ 2 } }{ 2(7 \times 5) } =$$

Evaluate

$$\frac{83}{70}\approx 1.185714286$$

Solution Steps

Calculate 5 to the power of 2 and get 25.

$$\frac{25+3^{2}+7^{2}}{2\times 7\times 5}$$

Calculate 3 to the power of 2 and get 9.

$$\frac{25+9+7^{2}}{2\times 7\times 5}$$

Add 25 and 9 to get 34.

$$\frac{34+7^{2}}{2\times 7\times 5}$$

Calculate 7 to the power of 2 and get 49.

$$\frac{34+49}{2\times 7\times 5}$$

Add 34 and 49 to get 83.

$$\frac{83}{2\times 7\times 5}$$

Multiply 2 and 7 to get 14.

$$\frac{83}{14\times 5}$$

Multiply 14 and 5 to get 70.

$$\frac{83}{70}$$

Factor

$$\frac{83}{2 \cdot 5 \cdot 7} = 1\frac{13}{70} = 1.1857142857142857$$
