Làm hộ mình bài 1 với ạ. Mình cảm ơn trước nha
1) \(\sqrt{96}=\sqrt{16.6}=4\sqrt{6}\)
2) \(\sqrt{500}=\sqrt{100.5}=10\sqrt{5}\)
3) \(\sqrt{49.360}=\sqrt{49.36.10}=42\sqrt{10}\)
4) \(\sqrt{125a^2}=\sqrt{5^3a^2}=5a\sqrt{5}\)
5) \(\sqrt{7x^2}=x\sqrt{7}\)
6) \(\sqrt{8y^2}=\sqrt{4.2y^2}=2y\sqrt{2}\)
7) \(\sqrt{25x^3}=\sqrt{5^2x^3}=5x\sqrt{x}\)
8) \(\sqrt{\left(1-x\right)^3}=\left(1-x\right)\sqrt{1-x}\)
9) \(\sqrt{8\left(a-5\right)^2}=\sqrt{4.2\left(a-5\right)^2}=\left(2a-10\right)\sqrt{2}\)
10) \(\sqrt{\dfrac{5\left(a-b\right)^3}{4}}=\dfrac{\left(a-b\right)\sqrt{5a-5b}}{2}\)
