Apply the product of powers property to a monomial algebraic expression: (5x^-1)(5x^-3)

forgot how to do it :/

When the bases are the same, keep that base and add the powers:
Ex: (a^2)(a^5)=a^7.
Or. (axa)(axaxaxaxa )=a^7

When multiplying powers with the same base just add the exponents. Your answer would be 5^-4

This is wrong.

No it isn't... Plug it into a calculator... Maybe you should go back to 8th grade math oh wait.... Maybe you're only in 6th grade

If that were (5^-1)(5^-3) you would be right, but that x changes things.
You have
(5x-1)(5x^-3) =
Use Associative Property of Multiplication.
5(x^-1)(5)(x^-3) =
Use Commutative Property of Multiplication.
5(5)(x^-1)(x^-3) =
25x^-4

Did you think that x means "times?"

5x^4When it's a negative exponent it's one over the number but change the negative exponent to a positive

No, it's 25/x^4 or 25x^-4.
