Suha wants to buy new carpet for her office building floor. The floor is in the shape of a rectangle. Its length is 15 meters and its width is 9 meters. Suppose carpet costs 13 for each square meter. How much will carpet cost for the floor?

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

faster, im not sure why but i know it is faster
