$9\frac{1}3*4*6\frac{1}{2}= \\ =\frac{28}3*4*\frac{13}2= \\ =\frac{28*4*13}{3*2}= \\ =\frac{28*13*2}3= \\ =\frac{728}3 \\ \\ 5\frac{3}{4}*8*2\frac{1}{2}=\frac{23}4*8*\frac{5}{2}=\frac{23*8*5}{4*2}=23*5=115$
[EDIT: Replaced x by * since x doesn't look well in typefaced math]

Answer:

A) $5^3*5^{-4}=5^{3-4}=5^{-1}=\frac{1}{5}$ (Yes. It has a value between zero and one.)

B) $\frac{3^5}{3^{-6}}=3^{5-\left(-6\right)}=3^{5+6}=3^{11}=177147$ (No. It does not have a value between zero and one.)

C) $\left(\frac{1}{4}\right)^3* \left(\frac{1}{4}\right)^2=\left(\frac{1}{4}\right)^{3+2}=\left(\frac{1}{4}\right)^5=\frac{1^5}{4^5}=\frac{1}{1024}$ . (Yes. It has a value between zero and one.)

D) $\frac{\left(-7\right)^5}{\left(-7\right)^7}=\left(-7\right)^{5-7}=\left(-7\right)^{-2}=\frac{1}{\left(-7\right)^2}=\frac{1}{49}$ (Yes. It has a value between zero and one.)
