Question

Here is any expert solve this. THIS QUESTION IS FROM, CHAPTER > EXPONENTS AND RADICALS. PLZZ solve it. all three

Answer 1

I assume you know the basic laws of exponents which will be used here.

1:
$({2x})^{ \frac{1}{6} } \times ({2x})^{ \frac { - 7}{6} } \\ ( {2x})^{ \frac{ - 6}{6} } \\ ( {2x} ) ^{ - 1} \\ \frac{1}{2x}$
2:
$(\sqrt[4]{( \frac{1}{x})^{ - 12}} ) ^{ \frac{ - 2}{3} } \\ ((\frac{1}{x}) ^{ - 3} )^{ \frac{ - 2}{3} } \\ ({x}^{3} )^{ \frac{ - 2}{3} } \\ \frac{1}{ {x}^{2} }$
3:
${a}^{ \frac{4}{7} } \div {a }^{ \frac{10}{7} } \\ {a}^{ \frac{4 - 10}{7} } \\ {a}^{ \frac{ - 6}{7} } \\ \frac{1}{ {a}^{ \frac{6}{7} } }$
