Answer:
10
Step-by-step explanation:
[tex] \frac{ \sqrt{75a} + \sqrt{12a} + \sqrt{27a} }{ \sqrt{3a} } \\ \frac{ \sqrt{(25 \times 3)a} + \sqrt{(4 \times 3)a} + \sqrt{(9 \times 3)a} }{ \sqrt{3a} } \\ \frac{ 5\sqrt{3a} + 2 \sqrt{3a} + 3\sqrt{3a} }{ \sqrt{3a} } \\ \frac{(5 + 2 + 3) \sqrt{3a} }{ \sqrt{3a} } = 10[/tex]
Answer: See below
My old math notebook had simillar question,hope that help
√75a+√12a-√27a/√3a
=√a(3*25)+√a(3*4)+√a(3*9)/√3a
=√25*√3a+√4*√3a+√9*√3a/√3a
=(5+2+3)√3a/√3a
=5+2+3=10
