    Hello,

    I presume that you want to calculate:

    \sqrt{\frac{25x^2 y^6}{121x^4}} = \frac{5xy^3}{11x^2}=\frac{5y^3}{11x}

    I hope I read this problem correctly:

    \frac{5x^2  \cdot  6a^2y}{25cx^2} \div\frac{ 12a^4x}{35cy} =

    Divison by a fraction is equal to the multiplication by it's reciprocal. So you get:

    \frac{5x^2  \cdot  6a^2y}{25cx^2} \cdot \frac{35cy }{12a^4x} =   \frac{5\cdot 6\cdot 35\cdot c\cdot x^2\cdot a^2\cdot y^2}{25\cdot 12\cdot c\cdot x^3 \cdot a^4}= \frac{7y^2}{2a^2\cdot x}

    Greetings
