# Evaluate (-3)^-2

In mathematics and computer “^” means power

**The answer is 1/9 or 0.111….**

## Below is how (-3)^-2 is calculated step by step

In this case we use the negative exponential rule

�−�=1��*b*−*n*=*b**n*1

the negative exponents rule tells us that to get rid of a negative exponent, the numerator is converted to a denominator and vice versa.

(-3)^-2 is the same as (-3)^{-2}

From the negative exponents rule above

. b = -3

. n = 2

When n (2) is taken to the denominator side it loses the negative sign as shown below

First calculate

(-3)^{-2} = (-3) x (-3) = 9

negative x negative is a positive

**Therefore the answer to (-3)^-2 is 1/9**

Proper fraction form:

1991

Decimal fraction form: 0.111…
