Question

son radicaciónes me pueden ayudar❤ xfa​

Answer 1

1)

$2\sqrt{12}-3\sqrt{75}+\sqrt{27}$

------------------------------

• $2\sqrt{12}=4\sqrt{3}$
• $3\sqrt{75}=15\sqrt{3}$
• $\sqrt{27}=3\sqrt{3}$

------------------------------

$=4\sqrt{3}-15\sqrt{3}+3\sqrt{3}\\=-8\sqrt{3}$

2)

$\sqrt{24}-5\sqrt{6}+\sqrt{486}$

------------------------------

• $\sqrt{24}=2\sqrt{6}$
• $\sqrt{486}=9\sqrt{6}$

------------------------------

$=2\sqrt{6}-5\sqrt{6}+9\sqrt{6}\\=6\sqrt{6}$

3)

$2\sqrt{5}+\sqrt{45}+\sqrt{180}-\sqrt{80}$

--------------------------------------

• $\sqrt{45}=3\sqrt{5}$
• $\sqrt{180}=6\sqrt{5}$
• $\sqrt{80}=4\sqrt{5}$

--------------------------------------

$=2\sqrt{5}+3\sqrt{5}+6\sqrt{5}-4\sqrt{5}\\=7\sqrt{5}$

4)

$\sqrt[3]{54}-\sqrt[3]{16}+\sqrt[3]{250}$

--------------------------------

• $\sqrt[3]{54}=3\sqrt[3]{2}$
• $\sqrt[3]{16}=2\sqrt[3]{2}$
• $\sqrt[3]{250}=5\sqrt[3]{2}$

--------------------------------

$=3\sqrt[3]{2}-2\sqrt[3]{2}+5\sqrt[3]{2}\\=6\sqrt[3]{2}$
