Question

if X equal to 7 minus 4 root 3 by 7 + 4 root 3 find the value of minus root x minus one by root x​

Answer 1

Answer:

-((7-4√3)²+1)/(7-4√3)

Step-by-step explanation:

1) Rationalise the denominator by multiplying the expression by (7-4√3)/(7-4√3) --> Which is essentially equal to 1.

2) Denominator becomes 1 on further solving with the numerator equal to (7-4√3)²

3) So X is a square term. √X  is (7-4√3).

4) Apply to the given expression to simplify expression.
