Answer 1

$(a^{2}\cdot b^{2})^{-1}:(a^{-2}\cdot a^{1})^{2}\\\\\\ \left(\dfrac{1}{a^{2}\cdot b^{2}}\right):\left(a^{-2+1}\right)^{2}\\\\\\ \left(\dfrac{1}{a^{2}\cdot b^{2}}\right):\left(a^{-1}\right)^{2}\\\\\\ \left(\dfrac{1}{a^{2}\cdot b^{2}}\right):a^{-1\cdot 2}\\\\\\ \left(\dfrac{1}{a^{2}\cdot b^{2}}\right):a^{-2}\\\\\\ \left(\dfrac{1}{a^{2}\cdot b^{2}}\right):\left(\dfrac{1}{a^{2}}\right)\\\\\\ \left(\dfrac{1}{\not a^{2}\cdot b^{2}}\right)\cdot \not a^{2}\\\\\\ \dfrac{1}{b^{2}}$
