c-)√50+√18−√8
d-)4√63−√7

me ajudem gente!!!!​

Answer 1

a)

$2\sqrt{27} -5\sqrt{12} \\2\sqrt{3*3*3} -5\sqrt{2*2*3}\\2*3\sqrt{3} -5*2\sqrt{3}\\6\sqrt{3} -10\sqrt{3}\\-4\sqrt{3}$

b)

$\sqrt{12} +\sqrt{75}+ \sqrt{108} \\\sqrt{2*2*3} +\sqrt{3*5*5}+ \sqrt{2*2*3*3*3} \\2\sqrt{3} +5\sqrt{3}+ 6\sqrt{3} \\13\sqrt{3}$

c)

$\sqrt{50} +\sqrt{18}- \sqrt{8} \\\sqrt{2*5*5} +\sqrt{2*3*3}- \sqrt{2*2*2} \\5\sqrt{2} +3\sqrt{2}- 3\sqrt{2} \\5\sqrt{2}$

d)

$4\sqrt{63}- \sqrt{7} \\4\sqrt{3*3*7}- \sqrt{7}\\4*3\sqrt{7}- \sqrt{7}\\12\sqrt{7}- \sqrt{7}\\11\sqrt{7}$
