Solve sqrt{4+2(2)(5)(5)-7(1)*7(1)}

$$\sqrt{ 4+2(2)(5)(5)-7(1) \times 7(1) }$$

Evaluate

$$\sqrt{55}\approx 7.416198487$$

Solution Steps

Multiply 2 and 2 to get 4.

$$\sqrt{4+4\times 5\times 5-7\times 1\times 7\times 1}$$

Multiply 4 and 5 to get 20.

$$\sqrt{4+20\times 5-7\times 1\times 7\times 1}$$

Multiply 20 and 5 to get 100.

$$\sqrt{4+100-7\times 1\times 7\times 1}$$

Add 4 and 100 to get 104.

$$\sqrt{104-7\times 1\times 7\times 1}$$

Multiply 7 and 1 to get 7.

$$\sqrt{104-7\times 7\times 1}$$

Multiply 7 and 7 to get 49.

$$\sqrt{104-49\times 1}$$

Multiply 49 and 1 to get 49.

$$\sqrt{104-49}$$

Subtract 49 from 104 to get 55.

$$\sqrt{55}$$
