c. [tex]\sqrt{27}+5\sqrt{3} -3\sqrt{75}[/tex]
= [tex]\sqrt{27} =3\sqrt{3}[/tex]
= [tex]3\sqrt{75}=15\sqrt{3}[/tex]
= [tex]3\sqrt{3}+5\sqrt{3}-15\sqrt{3}[/tex]
= [tex]-7\sqrt{3}[/tex] Final Answer
d. [tex]\sqrt{8x^3} + \sqrt{2x^3}-3x\sqrt{50x}[/tex]
= [tex]\sqrt{8x^3} =2\sqrt{2x}\sqrt{x}[/tex]
= [tex]\sqrt{2x^3} =\sqrt{2x}\sqrt{x}[/tex]
= [tex]3x\sqrt{50x} = 15\sqrt{2x} \sqrt{x}[/tex]
= [tex]2\sqrt{2x}\sqrt{x} + \sqrt{2x} \sqrt{x} -15\sqrt{2x} \sqrt{x}[/tex]
=[tex]-12\sqrt{2x}\sqrt{x}[/tex] Final Answer
