Solve 7-(-5)^2+(-3)^3*2-36:(-2)^2

$$7 - ( - 5 ) ^ { 2 } + ( - 3 ) ^ { 3 } \cdot 2 - 36 : ( - 2 ) ^ { 2 }$$

Evaluate

$$-81$$

Solution Steps

Calculate -5 to the power of 2 and get 25.

$$7-25+\left(-3\right)^{3}\times 2-\frac{36}{\left(-2\right)^{2}}$$

Subtract 25 from 7 to get -18.

$$-18+\left(-3\right)^{3}\times 2-\frac{36}{\left(-2\right)^{2}}$$

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

$$-18-27\times 2-\frac{36}{\left(-2\right)^{2}}$$

Multiply -27 and 2 to get -54.

$$-18-54-\frac{36}{\left(-2\right)^{2}}$$

Subtract 54 from -18 to get -72.

$$-72-\frac{36}{\left(-2\right)^{2}}$$

Calculate -2 to the power of 2 and get 4.

$$-72-\frac{36}{4}$$

Divide 36 by 4 to get 9.

$$-72-9$$

Subtract 9 from -72 to get -81.

$$-81$$

Factor

$$-81$$
