Which expression has a value of 15, using only four 4s and any of the following: + , – , · , ÷, exponents, and/or parentheses? a. 44 – (4 ÷ 4) b. (4 · 4) – (4 + 4) c. (4 · 4) – (4 ÷ 4) d. (4 + 4 + 4) ÷ 4

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

answer: 20
