Solve -2^5+2^7-2^6+2^2-2+1

$$- 2 ^ { 5 } + 2 ^ { 7 } - 2 ^ { 6 } + 2 ^ { 2 } - 2 + 1$$

Evaluate

$$35$$

Solution Steps

Calculate 2 to the power of 5 and get 32.

$$-32+2^{7}-2^{6}+2^{2}-2+1$$

Calculate 2 to the power of 7 and get 128.

$$-32+128-2^{6}+2^{2}-2+1$$

Add -32 and 128 to get 96.

$$96-2^{6}+2^{2}-2+1$$

Calculate 2 to the power of 6 and get 64.

$$96-64+2^{2}-2+1$$

Subtract 64 from 96 to get 32.

$$32+2^{2}-2+1$$

Calculate 2 to the power of 2 and get 4.

$$32+4-2+1$$

Add 32 and 4 to get 36.

$$36-2+1$$

Subtract 2 from 36 to get 34.

$$34+1$$

Add 34 and 1 to get 35.

$$35$$

Factor

$$5\times 7$$
