Answer:
Step-by-step explanation:
I am not clear your question.
5^(-2) / ( 5^(-3) * 5^(4))
When base is equal at multifaction index should be add.
ie. (-3) + 4 =1
5^(-2) / ( 5^((-3) +4))
5^(-2) / ( 5^(1))
When base is equal at division index should be substract.
5^(-2) / ( 5^(1))
5^((-2 )+ (-1) )
5^(-3)
We know a^(-2)= 1/ a^2
1/ 5^(3)
