1.
\(\sqrt{a}.\sqrt{\frac{32}{a}}=\sqrt{a.\frac{32}{a}}=\sqrt{32}=\sqrt{4^2.2}=4\sqrt{2}\)
2.
\(\sqrt{3,6a}.\sqrt{10a^3}=\sqrt{3,6a.10a^3}=\sqrt{36a^4}=\sqrt{(6a^2)^2}=6a^2\)
3.
\(\sqrt{0,5a}.\sqrt{50a^3}=\sqrt{0,5a.50a^3}=\sqrt{25a^4}=\sqrt{(5a^2)^2}=5a^2\)
4.
\(\sqrt{2a^3}.\sqrt{50a}=\sqrt{2a^3.50a}=\sqrt{100a^4}=\sqrt{(10a^2)^2}=10a^2\)
Em cần cụ thể bài nào thì nhờ mọi người nha, đừng up lên không nói gì như thế là không tôn trọng em ạ!
