Question

Simplify (5x^-1/x^3)^-1

Answer 1

equals to what ??

Answer 2

\[(\frac{ 5x ^{-1} }{ x ^{3} })^{-1}\]
Here. this should look better.
And these are the options:
a) x^4/5
b) -x^4/5
c) 5/x^4
d) x^3/5

Answer 3

x^-1=1/x
so (5/x^3)*1/x= 5/x^4
now (5/x^4)^-1
u turn this upside down
so x^4/5 is the ans :p

Answer 4
