Question

pls answer fast . check opt A,C with process ​

Answer 1

Answer:

B) $3\sqrt{4},   4\sqrt{5},   4\sqrt{7}$

Step-by-step explanation:

A) $4\sqrt{5} =\sqrt{4^{2} *5}=\sqrt{80}  \\3\sqrt4} =\sqrt{3^{2} *4}=\sqrt{36}  \\4\sqrt{7} =\sqrt{4^{2} *7}=\sqrt{112}$

B) $3\sqrt{4} =\sqrt{3^{2} *4} =\sqrt{36} \\4\sqrt{5} =\sqrt{4^{2} *5} =\sqrt{80} \\4\sqrt{7} =\sqrt{4^{2} *7} =\sqrt{112}$

C) $3\sqrt{4} =\sqrt{3^{2} *4} =\sqrt{36} \\4\sqrt{7} =\sqrt{4^{2} *7} =\sqrt{112} \\3\sqrt{8} =\sqrt{3^{2} *8} =\sqrt{72}$
