Three computers can print out a task in 4 min, 6 min, and 12 min, respectively. how long would it take to complete the task with all three computers working?

12 min

Step-by-step explanation:

Because the other computers take less time you then pick the longest time because the 12 min one wouldn't be done in 4 or 6 mins

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
