Solve -1^4+2*(-3)^2-5div1/2*2

$$- 1 ^ { 4 } + 2 \times ( - 3 ) ^ { 2 } - 5 \div \frac { 1 } { 2 } \times 2$$

Evaluate

$$-3$$

Solution Steps

Calculate 1 to the power of 4 and get 1.

$$-1+2\left(-3\right)^{2}-\frac{5}{\frac{1}{2}}\times 2$$

Calculate -3 to the power of 2 and get 9.

$$-1+2\times 9-\frac{5}{\frac{1}{2}}\times 2$$

Multiply 2 and 9 to get 18.

$$-1+18-\frac{5}{\frac{1}{2}}\times 2$$

Add -1 and 18 to get 17.

$$17-\frac{5}{\frac{1}{2}}\times 2$$

Divide 5 by \frac{1}{2} by multiplying 5 by the reciprocal of \frac{1}{2}.

$$17-5\times 2\times 2$$

Multiply 5 and 2 to get 10.

$$17-10\times 2$$

Multiply 10 and 2 to get 20.

$$17-20$$

Subtract 20 from 17 to get -3.

$$-3$$

Factor

$$-3$$
