√49y^14
separate the function
V49 x Vy^14
7 x y^7 --- just divide the exponent in half
7y^7
200/233=x/100
233x=20,000
20,000/233=85.8369
85.8369-100=-14.163%
Meaning there was a 14.163 percent decrease.

Answer: X = kuv/ (u+v)
that means that x(u+v)/(uv) = k, a constant. so you want x such that,
x(3+3)/(3*3) = 3(3+1)/(3*1)
x=6
