The size of a tv set is described by the
length of a diagonal of the screen.
one tv is labelled 27 inches, which is
about 70 cm. the screen is 40 cm high.
what is the width of the screen?
give your answer to one decimal place.

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: -1
