Final answer:
The expression (2ay^-4)/(b^5) can be simplified by recalling the rule that a^-n = 1/a^n, converting negative exponents to positive. Hence, the expression gets simplified to (2a/(b^5y^4)).
Step-by-step explanation:
To simplify the expression (2ay-4)/(b5) and rewrite it without negative exponents, you need to understand the rules of exponents. Specifically, any number with a negative exponent is equal to the reciprocal of that number with a positive exponent. So, a-n is equal to 1/an. Therefore, we can rewrite y-4 as 1/y4. Also, since 5 is a positive exponent, there's no need to change b5.
So, the simplified form of the original expression without negative exponents is: (2a/(b5y4)).
Even though the original question had a typo with the number 120, I've clarified the steps needed for simplifying the original expression written as (2ay-4)/(b5).
