Question

......√(900/20)+√(625/5)-√(1125/25).............

Answer 1

$\sqrt{\frac{900}{20}^{(20} } +\sqrt{\frac{625}{5} } -\sqrt{\frac{1125}{25} } =$

$\sqrt{45} +\sqrt{\frac{625}{5}^{(5} } -\sqrt{\frac{1125}{25} } =$

$\sqrt{45} +\sqrt{125} -\sqrt{\frac{1125}{35}^{(25}} =$

$\sqrt{45} +\sqrt{125} -\sqrt{45} =$

$3\sqrt{5} +5\sqrt{5} -3\sqrt{5} =5\sqrt{5}$
