Question

mean of x,x√2,x√3,x√3,x√3 is 5 then find x?​

Answer 1

Answer:

mean of x,x√2,x√3,x√3,x√3 is 5

Then,

$\frac{x + x \sqrt{2} + x \sqrt{3} + x \sqrt{3} x + \sqrt{3} }{5} = 5 \\ \frac{x + x \sqrt{2} + 3x \sqrt{3} }{5} = 5 \\ x(1 + \sqrt{2} + \sqrt{3} ) = 25 \\ x = \frac{25}{(1 + \sqrt{2} + \sqrt{3}) }$

x = 6.0295
