Question

Answer 1

d, \(\dfrac{5\sqrt{16.3}-3\sqrt{9.3}+2\sqrt{4.3}}{3}\)

= \(\dfrac{20\sqrt{3}-9\sqrt{3}+4\sqrt{3}}{3}\)

= \(\dfrac{15\sqrt{3}}{3}\) =\(5\sqrt{3}\)

e,\(\dfrac{\sqrt{16.2}-\sqrt{25.2}+\sqrt{4.2}}{\sqrt{2}}\)

=\(\dfrac{4\sqrt{2}-5\sqrt{2}+2\sqrt{ }2}{\sqrt{2}}\) = \(\dfrac{\sqrt{2}}{\sqrt{2}}\)  = 1

Answer 2

mình chỉ giúp đc từng  đó nha bn mong thông cảm 

 

Answer 3

bài 1

a, \(\dfrac{\sqrt{3}}{\sqrt{25.3}}\)  = \(\dfrac{\sqrt{3}}{5\sqrt{3}}\)  =5

b, \(\dfrac{\sqrt{444}}{\sqrt{111}}\)  = 4
