How do you simplify #1/ (7x^-4y^-1)# with positive exponents?
Simplified, your expression is equivalent to
All negative exponents with non-zero bases hold the following identity:
To be sure that this question can be sensibly solved, I will also elaborate that a reciprocal is a self-inverse function.
Much like subtraction (Example: (
So in short:
Applying the first demonstrated identity will look like so:
Now we will apply the second demonstrated rule:
Yielding the simplified expression.
