Solve 12-5*sqrt{81}+sqrt{25}div(-5)+2*(-3)^3

$$12 - 5 * \sqrt { 81 } + \sqrt { 25 } \div ( - 5 ) + 2 * ( - 3 ) ^ { 3 }$$

Evaluate

$$-88$$

Solution Steps

Calculate the square root of 81 and get 9.

$$12-5\times 9+\frac{\sqrt{25}}{-5}+2\left(-3\right)^{3}$$

Multiply -5 and 9 to get -45.

$$12-45+\frac{\sqrt{25}}{-5}+2\left(-3\right)^{3}$$

Subtract 45 from 12 to get -33.

$$-33+\frac{\sqrt{25}}{-5}+2\left(-3\right)^{3}$$

Calculate the square root of 25 and get 5.

$$-33+\frac{5}{-5}+2\left(-3\right)^{3}$$

Divide 5 by -5 to get -1.

$$-33-1+2\left(-3\right)^{3}$$

Subtract 1 from -33 to get -34.

$$-34+2\left(-3\right)^{3}$$

Calculate -3 to the power of 3 and get -27.

$$-34+2\left(-27\right)$$

Multiply 2 and -27 to get -54.

$$-34-54$$

Subtract 54 from -34 to get -88.

$$-88$$

Factor
