How do you simplify #x^2y^-4*x^3y^2# and write it using only positive exponents?
This is the same as:
However, it is good practice to use the same format as in the question.
This is just a long multiplication problem. All the variables are factors, even though there is one multiplication dot written between two of the factors.
That means you can just write this out as four factors, like this:
You can re-group the factors for your own convenience
To multiply like bases, you add their exponents
This comes out to
To clear the minus sign on the exponent of
