Answer 1

Answer:

$\mathrm{D.} \: (\frac{5}{4} )^{\frac{7}{2}$

Step-by-step explanation:

$\sqrt{(\frac{5}{4})^7 }$

Apply rule : $\sqrt{a} =a^{\frac{1}{2} }$

$((\frac{5}{4})^7 )^{\frac{1}{2} }$

Apply rule : $(a^b)^c=a^{bc}$

$(\frac{5}{4} )^{7 \times \frac{1}{2} }$

$(\frac{5}{4} )^{\frac{7}{2}$
