Answer 1

Answer:

$4 - \frac{5}{ \sqrt{75} }$

Taking LCM .Then

$\frac{4 \sqrt{75} - 5}{ \sqrt{75} }$

Then rationalise it by multi plying both numerator and denominator by root 75.

$\frac{4 \times 75 - 5 \sqrt{75} }{75}$

Taking 5 as common.

$\frac{5(4 \times 15 - \sqrt{75)} }{75}$

$\frac{60 - \sqrt{75} }{15}$

I hope this helps you
