A =\(\frac{\sqrt{32}}{\sqrt{128}}\).\(\frac{\sqrt{x^6y^4}}{\sqrt{x^6y^6}}\)
A = \(\sqrt{\frac{32}{128}}\).\(\sqrt{\frac{x^6y^4}{x^6y^6}}\)
A = \(\sqrt{\frac{1}{4}}\).\(\sqrt{\frac{1}{y^2}}\)
A = \(\frac{1}{2}\).\(\frac{1}{\left|y\right|}\)
Thế x = 2013 , y = 0,5 , ta được:
A = \(\frac{1}{2.0,5}\)= 1
