Hello student,
Please find the answer to your question below
Given
\frac{81^{-7/4}-81^{-3/4}}{81^{5/4}}
By shifting denominator to numerator by using property am/an=am-nwe get
=(81)(-7/4)-(5/4)-(81)(-3/4)-(5/4)
=(81)(-12/4)-(81)(-8/4)
=(34)(-12/4)-(34)(-8/4)
=3-12-3-8
=(1/312)-(1/38)
=(312-38)/312
=0.9876
