Solve -3x[-5^0-(-1)^3]-|-7|

$$- 3 x [ - 5 ^ { 0 } - ( - 1 ) ^ { 3 } ] - | - 7 |$$

Evaluate

$$-7$$

Solution Steps

Calculate 5 to the power of 0 and get 1.

$$-3x\left(-1-\left(-1\right)^{3}\right)-|-7|$$

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

$$-3x\left(-1-\left(-1\right)\right)-|-7|$$

The opposite of -1 is 1.

$$-3x\left(-1+1\right)-|-7|$$

Add -1 and 1 to get 0.

$$-3x\times 0-|-7|$$

Multiply -3 and 0 to get 0.

$$0x-|-7|$$

Anything times zero gives zero.

$$0-|-7|$$

The absolute value of a real number a is a when a\geq 0, or -a when a<0. The absolute value of -7 is 7.

$$0-7$$

Subtract 7 from 0 to get -7.

$$-7$$

Factor

$$-7$$
