Question

$a - \sqrt{ \frac{5}{a} } = 6$
$a + \sqrt{5a} = x$
Can you please help me to find the x? ​

Answer 1

Of course, my friend, take this:

Answer: x=6+3$\sqrt{5}$.

Step by step solution:

1. a-$\sqrt\frac{5}{a}$=6

a=5

a=$\frac{7+3\sqrt{5} }2}$

a=$\frac{7-3\sqrt{5} }{2}$

2. (a, x)=($\frac{7+3\sqrt{5} }{2}$, 6+3$\sqrt{5}$).
