Solve -2^4+4--2^3-2(-2)-8

$${ -2 }^{ 4 } +4- { -2 }^{ 3 } -2(-2)-8$$

Evaluate

$$24$$

Solution Steps

Calculate -2 to the power of 4 and get 16.

$$16+4-\left(-2\right)^{3}-2\left(-2\right)-8$$

Add 16 and 4 to get 20.

$$20-\left(-2\right)^{3}-2\left(-2\right)-8$$

Calculate -2 to the power of 3 and get -8.

$$20-\left(-8\right)-2\left(-2\right)-8$$

The opposite of -8 is 8.

$$20+8-2\left(-2\right)-8$$

Add 20 and 8 to get 28.

$$28-2\left(-2\right)-8$$

Multiply 2 and -2 to get -4.

$$28-\left(-4\right)-8$$

The opposite of -4 is 4.

$$28+4-8$$

Add 28 and 4 to get 32.

$$32-8$$

Subtract 8 from 32 to get 24.

$$24$$

Factor

$$2^{3}\times 3$$
