Solve (-2)^2+8(-3)^0-5(-3)^2=

$$( - 2 ) ^ { 2 } + 8 ( - 3 ) ^ { 0 } - 5 ( - 3 ) ^ { 2 } =$$

Evaluate

$$-33$$

Solution Steps

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

$$4+8\left(-3\right)^{0}-5\left(-3\right)^{2}$$

Calculate -3 to the power of 0 and get 1.

$$4+8\times 1-5\left(-3\right)^{2}$$

Multiply 8 and 1 to get 8.

$$4+8-5\left(-3\right)^{2}$$

Add 4 and 8 to get 12.

$$12-5\left(-3\right)^{2}$$

Calculate -3 to the power of 2 and get 9.

$$12-5\times 9$$

Multiply 5 and 9 to get 45.

$$12-45$$

Subtract 45 from 12 to get -33.

$$-33$$

Factor
