@karan000 the answer choices are A. -(7-7√2)/(2 B. -(7+7√2)/(2) C. (4+6√3)/(3) D (2+7√3)/(2)

Multiply numerator and denominator by the conjugate of the denominator.

4. Mertsj

$\frac{7}{1-\sqrt{3}}\times \frac{1+\sqrt{3}}{1+\sqrt{3}}$

7. Mertsj

You multiply two fractions by multiplying the numerators and multiplying the denominators.
