Answer:
g. 14√2
h. 50x√(5x)
Step-by-step explanation:
Find the perfect squares under the radical and factor out their square root. Combine like terms in the usual way.
g.
[tex]2\sqrt{50}+2\sqrt{8}=2\sqrt{5^2\cdot 2}+2\sqrt{2^2\cdot 2}=2\sqrt{2}(5+2)\\\\=14\sqrt{2}[/tex]
__
h.
[tex]11\sqrt{245x^3}-9\sqrt{45x^3}=11\sqrt{7^2\cdot 5x^2\cdot x}-9\sqrt{3^2\cdot 5x^2\cdot x}\\\\=77x\sqrt{5x}-27x\sqrt{5x}=50x\sqrt{5x}[/tex]
