Answer:
[tex] \sqrt{50x^2} [/tex]
[tex] \sqrt{72x^2} [/tex]
Step-by-step explanation:
Simplify each given options as much as possible to see which of them has a result that is like a radical.
Option 1: [tex] \sqrt{50x^2} [/tex]
[tex] \sqrt{25*2*x^2} = 5x\sqrt{2} [/tex]
This is like a radical
Option 2: [tex] \sqrt{32x} [/tex]
[tex] \sqrt{16*2*x} = 4\sqrt{2x} [/tex]
This is NOT like a radical
Option 3: [tex] \sqrt{18n} [/tex]
[tex] \sqrt{9*2*n} = 3\sqrt{2n} [/tex]
This is NOT like a radical
Option 4: [tex] \sqrt{72x^2} [/tex]
[tex] \sqrt{36*2*x^2} = 6x\sqrt{2} [/tex]
This is like a radical
