Виконай ділення. a) 1/〖3ax〗^2 : 1/(〖9a〗^2 x) = 1/〖3ax〗^2 • (〖9a〗^2 x)/1 = 3a/x; б) 〖6x〗^2/y : 〖1,5x〗^3/y^2 = (〖6x〗^2•y^2 )/(y• 〖1,5x〗^3 ) = 4y/x; в) 14/〖5x〗^3 : 7x/〖2y〗^2 = (14• 〖2y〗^2)/(〖5x〗^3•7x) = 〖4y〗^2/〖5x〗^4 ; г) 2a/3x : 〖4a〗^2/9x = (2a•9x)/(3x• 〖4a〗^2 ) = 3/2a; ґ) 〖18c〗^2/5xy : 〖9c〗^3/〖15x〗^2 = (〖18c〗^2•〖15x〗^2 )/(5xy• 〖9c〗^3 ) = (2•3x)/cy = 6x/cy; д) 〖18z〗^3/〖xy〗^2 : 〖9z〗^3/(x^2 y) = (〖18z〗^3•x^2 y )/(〖xy〗^2• 〖9z〗^3 ) = 2x/y.
