Evaluate -(57)^0+(1/2)^-2-1^5

$- {(57)}^{0} + {(\frac{1}{2})}^{- 2} - 1^{5}$

Step 1

Simplify each term.

Anything raised to $0$ is $1$ .

$- 1 \cdot 1 + {(\frac{1}{2})}^{- 2} - 1^{5}$

Multiply $- 1$ by $1$ .

$- 1 + {(\frac{1}{2})}^{- 2} - 1^{5}$

Change the sign of the exponent by rewriting the base as its reciprocal.

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

Raise $2$ to the power of $2$ .

$- 1 + 4 - 1^{5}$

One to any power is one.

$- 1 + 4 - 1 \cdot 1$

Multiply $- 1$ by $1$ .

$- 1 + 4 - 1$

Step 2

Simplify by adding and subtracting.

Add $- 1$ and $4$ .

$3 - 1$

Subtract $1$ from $3$ .

$2$
