Question

Найдите значения 4√19600-3√22500; √2,25-5√3600

Answer 1

$4\sqrt{196*100} -3\sqrt{225*100} =4*\sqrt{196}*\sqrt{100}-3\sqrt{225}*\sqrt{100} =10(4*14-3*15)=10(56-45)=110$$\\\sqrt{225/100} -5\sqrt{36*100}=\frac{\sqrt{225} }{100}-5\sqrt{36}\sqrt{100}=\frac{15}{10} -30*10=\frac{15-3000}{10}=\frac{-2985}{10}= -298,5$

Ответ: 110 и -298,5
