Simplify . Your answer should contain only positive exponents. ( a 1 2 b 1 2 ) − 1 \left(a^{\frac{1}{2}}b^{\frac{1}{2}}\right)^{-1} ( a 2 1 b 2 1 ) − 1

1 a 1 2 b 1 2 \frac{1}{a^{\frac{1}{2}}b^{\frac{1}{2}}} a 2 1 b 2 1 1

a 1 2 b 1 2 a^{\frac{1}{2}}b^{\frac{1}{2}} a 2 1 b 2 1

− 1 a 1 2 b 1 2 -\frac{1}{a^{\frac{1}{2}}b^{\frac{1}{2}}} − a 2 1 b 2 1 1

− a 1 2 b 1 2 -a^{\frac{1}{2}}b^{\frac{1}{2}} − a 2 1 b 2 1
