Solve -3*2^3+2*2^2-5*2+3

$$-3 \times { 2 }^{ 3 } +2 \times { 2 }^{ 2 } -5 \times 2+3$$

Evaluate

$$-23$$

Solution Steps

To multiply powers of the same base, add their exponents. Add 1 and 2 to get 3.

$$-3\times 2^{3}+2^{3}-5\times 2+3$$

Calculate 2 to the power of 3 and get 8.

$$-3\times 8+2^{3}-5\times 2+3$$

Multiply -3 and 8 to get -24.

$$-24+2^{3}-5\times 2+3$$

Calculate 2 to the power of 3 and get 8.

$$-24+8-5\times 2+3$$

Add -24 and 8 to get -16.

$$-16-5\times 2+3$$

Multiply 5 and 2 to get 10.

$$-16-10+3$$

Subtract 10 from -16 to get -26.

$$-26+3$$

Add -26 and 3 to get -23.

$$-23$$

Factor

$$-23$$
