Solve =-7(-1)^2+8(-1)^3-3(-1)^4+6

$$= - 7 ( - 1 ) ^ { 2 } + 8 ( - 1 ) ^ { 3 } - 3 ( - 1 ) ^ { 4 } + 6$$

Evaluate

$$-12$$

Solution Steps

Calculate -1 to the power of 2 and get 1.

$$-7+8\left(-1\right)^{3}-3\left(-1\right)^{4}+6$$

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

$$-7+8\left(-1\right)-3\left(-1\right)^{4}+6$$

Multiply 8 and -1 to get -8.

$$-7-8-3\left(-1\right)^{4}+6$$

Subtract 8 from -7 to get -15.

$$-15-3\left(-1\right)^{4}+6$$

Calculate -1 to the power of 4 and get 1.

$$-15-3\times 1+6$$

Multiply 3 and 1 to get 3.

$$-15-3+6$$

Subtract 3 from -15 to get -18.

$$-18+6$$

Add -18 and 6 to get -12.

$$-12$$

Factor

$$-12$$
