Question

If x+y : √xy. = 4 : 1, then find the value of x : y.
​

Answer 1

Step-by-step explanation:

apply hair formula of a + b square is equals to a square + b square + 2 a b take a a is equals to for under b is equals to 1 I mean to say take X is equals to 4 and Y is equals to 1 and now apply the formula of a + b square whole square you find the answer and maybe your answer is a 16 access care one square plus 8 xy something like this

Answer 2

Answer:

7+4√3

Step-by-step explanation:

(x+y)/√(xy) = 4/1

x+y = 4√(xy)  -----------------(1)

(x-y)² = (x+y)² - 4xy

(x-y)² = 16xy - 4xy

(x-y)² = 12xy

x-y = 2√(3xy)  ---------------(2)

(1) + (2)

2x = 2√(xy) (2+√3)

√(x/y) = (2+√3)

x/y = 4+3+4√3

x/y = 7+4√3

x:y = (7+4√3):1
