Solve 2^-2-(pi-1)^0+(-1)^4

$$2 ^ { - 2 } - ( \pi - 1 ) ^ { 0 } + ( - 1 ) ^ { 4 }$$

Evaluate

$$\frac{1}{4}=0.25$$

Solution Steps

Calculate 2 to the power of -2 and get \frac{1}{4}.

$$\frac{1}{4}-\left(\pi -1\right)^{0}+\left(-1\right)^{4}$$

Calculate \pi -1 to the power of 0 and get 1.

$$\frac{1}{4}-1+\left(-1\right)^{4}$$

Subtract 1 from \frac{1}{4} to get -\frac{3}{4}.

$$-\frac{3}{4}+\left(-1\right)^{4}$$

Calculate -1 to the power of 4 and get 1.

$$-\frac{3}{4}+1$$

Add -\frac{3}{4} and 1 to get \frac{1}{4}.

$$\frac{1}{4}$$

Factor

$$\frac{1}{2 ^ {2}} = 0.25$$
