How would you do this radical problem?

Question

(4/9) ^ -1/2

if u dont understand that, its saying four ninths to the negative half power

Answer 1

(4/9)^-1/2= (9/4)^1/2

(9/4)^1/2= (9^1/2)/(4^1/2)=3/2

Answer 2

In general , x^-2=1/x^2. This is a Law of Exponents.

Therefore, (4/9)^-1/2 = 1/ (4/9)^1/2

=1 / 2/3

=1/1 / 2/3

=1/1 X 3/2

=3/2
