1. -a^3 x b^3 x b^4/16a^4 x 243a^5/b^5 = -15,1875 a^4 x b^2
2. 4a^-2 x b^7 x 2b^3/a^2 = 4a^-4 x 2b^10
3. 36x^2 . 4y^2 / 3x . y^2 = 12x . 4y^4 / ( 4/3x^-1 . 9y )^2 =
12x . 4y^4 / 16/9x^-2 / 9y^2 = 27/4x^-1 . 4/9y^2
4. -p^3 x q^2 x r^3 / -3p^6 . -3q^3 = 3p^9 . 3q^5 x r^3 x -12q^2r^2/2pqr^3
-15,1875 a^4 x b^2
2. 4a^-2 x b^7 x 2b^3/a^2 = 4a^-2 x a^2 x 2b^10
4a^-4 x 2b^10
