Answer:
8
Step-by-step explanation:
Using the rules of exponents
[tex]\frac{a^{m} }{a^{n} }[/tex] = [tex]a^{(m-n)}[/tex] and [tex]a^{\frac{1}{2} }[/tex] = [tex]\sqrt{a}[/tex]
Given
[tex]\frac{64^{\frac{7}{10} } }{64^{\frac{1}{5} } }[/tex]
= [tex]64^{(\frac{7}{10}-\frac{1}{5}) }[/tex]
= [tex]64^{\frac{1}{2} }[/tex] = [tex]\sqrt{64}[/tex] = 8
