Express x^-1 y^-2/z^-3 with positive exponents.

Negative exponents work like this:

So, a number raised to a negative power simply means the multiplicative inverse of that number raised to the positive power.

So, in your case, you have

We can rework this expression to get

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5
