J)
= \sqrt[6]{ a^{2} } = \sqrt[3]{a}

k)
  = \sqrt[6]{ 2^{3} } = \sqrt{2}
l)
 
= \sqrt[8]{ 5^{2}. a^{2}  } = \sqrt[4]{5a}

m)
= \sqrt[4]{ 2^{7} } =2 \sqrt[4]{ 2^{3} }

n)
= \sqrt[12]{ 3^{3}. a^{3}  } = \sqrt[4]{3a}

o)
 = \sqrt{x. \sqrt[3]{ \sqrt{ x^{2} .x} } } = \sqrt{x \sqrt[6]{ x^{3} } } = \sqrt[12]{ x^{6}. x^{3}  } } = \sqrt[4]{ x^{3} }

p)
=    \frac{ \sqrt[8]{14}. \sqrt[8]{10}  }{ \sqrt[8]{2} }= \frac{ \sqrt[8]{140} }{ \sqrt[8]{2} } = \sqrt[8]{70}
