Answer 2

Answer:

Step-by-step explanation:

Given: x  =  √7  +   √3

To find: $\frac{x-4}{x}$

Putting the value of x,

$\frac{√7 + √3-4}{√7 +√3}$

Rationalizing the denominator,

$\frac{√7 + √3-4}{√7 +√3}$  ×  $\frac{√7 - √3}{√7 - √3}$

$\frac{(√7 + √3-4)(√7 - √3)}{7-3}$

$\frac{7-3-4√7 + 4√3}{4}$

$\frac{4-4√7 + 4√3}{4}$

$\frac{4(1-√7 + √3}{4}$

1 -   √7  +   √3
