(A) 2 ( b) 0 (c)√5 (d)7/√5 ​

Answer 1

$\sqrt{35} \div 5 \times \sqrt{7} \\ = \frac{ \sqrt{35} }{5} \times \sqrt{7} \\ = \frac{ \sqrt{5 \times 7} } {5} \times \sqrt{7} \\ = \frac{7 \sqrt{5} }{5} \\ = \frac{7 \sqrt{5} }{5} \times \frac{ \sqrt{5} }{ \sqrt{5} } \\ = \frac{35}{5 \sqrt{5} } \\ = \frac{7}{ \sqrt{5} }$

Therefore, Option (d) is correct
