Answer:
[tex]\frac{a - b}{c^{3}}[/tex]
Step-by-step explanation:
a = -3, b = 4, c = -5
given expression:
[tex]\frac{ -1 }{ 5 }[/tex] [tex]\frac{ 1 }{ 5 }[/tex] [tex]\frac{ -7 }{ 5 }[/tex]
= [tex]\frac{ 1 }{ c }[/tex] [tex]\frac{ -1 }{ c }[/tex] [tex]\frac{ a - b }{ -c }[/tex]
= [tex]\frac{-1}{c^{2} }[/tex] × [tex]\frac{a - b}{-c}[/tex]
= [tex]\frac{-1(a-b)}{(c^{2})(-c)}[/tex]
= [tex]\frac{a - b}{c^{3}}[/tex]
