Question

if x is equals to 7 minus 4 root 3 then find the value of root x + 1 upon root x​

Answer 1

Step-by-step explanation:

x=7-4✓3 so, 1/x=1/7-4✓3= 7+4✓3/1. so x +1/x will be = 14

Answer 2

The value of $\sqrt{x} +\frac{1}{\sqrt{x} } =4$

Step-by-step explanation:

$=> x=7-4\sqrt{3} \\=>x=(\sqrt{3} )^2+(2)^2-2\times2\times\sqrt{3} \\=>x=(2-\sqrt{3} )^2\\=>\sqrt{x} =2-\sqrt{3} \\=>\frac{1}{\sqrt{x} } =2+\sqrt{3}$on rationalizing

∴ $\sqrt{x} +\frac{1}{\sqrt{x} } =4$
