Solve (sqrt{81}-sqrt{36})-(6^2+2^2)

$$( \sqrt { 81 } - \sqrt { 36 } ) - ( 6 ^ { 2 } + 2 ^ { 2 } )$$

Evaluate

$$-37$$

Solution Steps

Calculate the square root of 81 and get 9.

$$9-\sqrt{36}-\left(6^{2}+2^{2}\right)$$

Calculate the square root of 36 and get 6.

$$9-6-\left(6^{2}+2^{2}\right)$$

Subtract 6 from 9 to get 3.

$$3-\left(6^{2}+2^{2}\right)$$

Calculate 6 to the power of 2 and get 36.

$$3-\left(36+2^{2}\right)$$

Calculate 2 to the power of 2 and get 4.

$$3-\left(36+4\right)$$

Add 36 and 4 to get 40.

$$3-40$$

Subtract 40 from 3 to get -37.

$$-37$$
