g⁻² = 1/g² = 1 / (g g)
Since g is multiplying g, hence the answer can not be negative. It can only be positive.
Because a negative negative = positive and
positive positive = positive.
The possible answer is option C or D.
if g = 3,
g⁻² = 1/g² = 1 / (g g)
3⁻² = 1/3² = 1 / (3 3) = 1/9
if g = 9
9⁻² = 1/9² = 1 / (9 9) = 1/81
Possible answer is C or D.
