Solve sqrt{(20-4)}-1/3*(6div2*sqrt{16})

$$\sqrt{ (20-4) } - \frac{ 1 }{ 3 } \times (6 \div 2 \times \sqrt{ 16 } )$$

Evaluate

$$0$$

Solution Steps

Subtract 4 from 20 to get 16.

$$\sqrt{16}-\frac{1}{3}\times \frac{6}{2}\sqrt{16}$$

Calculate the square root of 16 and get 4.

$$4-\frac{1}{3}\times \frac{6}{2}\sqrt{16}$$

Divide 6 by 2 to get 3.

$$4-\frac{1}{3}\times 3\sqrt{16}$$

Cancel out 3 and 3.

$$4-\sqrt{16}$$

Calculate the square root of 16 and get 4.

$$4-4$$

Subtract 4 from 4 to get 0.

$$0$$

Factor

$$0$$
