Solve -1^4+(3-7)^4-3*(-1)^1990+2

$$- 1 ^ { 4 } + ( 3 - 7 ) ^ { 4 } - 3 \times ( - 1 ) ^ { 1990 } + 2$$

Evaluate

$$254$$

Solution Steps

Calculate 1 to the power of 4 and get 1.

$$-1+\left(3-7\right)^{4}-3\left(-1\right)^{1990}+2$$

Subtract 7 from 3 to get -4.

$$-1+\left(-4\right)^{4}-3\left(-1\right)^{1990}+2$$

Calculate -4 to the power of 4 and get 256.

$$-1+256-3\left(-1\right)^{1990}+2$$

Add -1 and 256 to get 255.

$$255-3\left(-1\right)^{1990}+2$$

Calculate -1 to the power of 1990 and get 1.

$$255-3\times 1+2$$

Multiply 3 and 1 to get 3.

$$255-3+2$$

Subtract 3 from 255 to get 252.

$$252+2$$

Add 252 and 2 to get 254.

$$254$$

Factor

$$2\times 127$$
