Solve -7:(1)(pi-1)^0+(-1)^2000+(1/3)^-2-1

$$- 7 : ( 1 ) ( \pi - 1 ) ^ { 0 } + ( - 1 ) ^ { 2000 } + ( \frac { 1 } { 3 } ) ^ { - 2 } - 1$$

Evaluate

$$2$$

Solution Steps

Anything divided by one gives itself.

$$-7\left(\pi -1\right)^{0}+\left(-1\right)^{2000}+\left(\frac{1}{3}\right)^{-2}-1$$

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

$$-7+\left(-1\right)^{2000}+\left(\frac{1}{3}\right)^{-2}-1$$

Calculate -1 to the power of 2000 and get 1.

$$-7+1+\left(\frac{1}{3}\right)^{-2}-1$$

Add -7 and 1 to get -6.

$$-6+\left(\frac{1}{3}\right)^{-2}-1$$

Calculate \frac{1}{3} to the power of -2 and get 9.

$$-6+9-1$$

Add -6 and 9 to get 3.

$$3-1$$

Subtract 1 from 3 to get 2.

$$2$$

Factor

$$2$$
