no.............it means y would equal 1/3^2.
when you have a negative exponent, you just invert the number. For example, x^-2 is the same as 1/x^2.
Hope that helps.

Nope it means y= 1/ 3^2

No.
A negative power means the number is "one over" i.e. x becomes 1/x
So in this case y = 3^-2 means y = 1/3^2 or y = 1/9

3^-2 = (3^-1)^2
3^-1 = 1/3 ... the minus indicates you find the reciprocal
so (3^-1)^2 = 1/9

No.
One of the laws of exponents is that,
y = x^(-m) = 1 / (x^m)
so,
y = 3^(-2) = 1 / (3^2) = 1 / 9

No.
3^(-2) = 1/3^2 = 1/9
But you're starting to get the picture. Keep after it âº

x ^ - n = 1/x^n
So....
y = 3^-2
y = 1/3^2 or
y = 1/9
