Question

Find the sub-duplicate ratio of 9x²a² : 25y^6 b²​

Answer 1

Answer:

S.D.R =

$\sqrt{ \frac{9 {x}^{2} {a}^{2} }{25 {y}^{6} {b}^{2} } } = \frac{3xa}{5 {y}^{3} b}$

= 3xa : 5y³b

Answer 2

Answer:

$\sf S. \: D. \: R = \sqrt{ \dfrac{9 {x}^{2} {a}^{2} }{25 {y}^{6} {b}^{2} } } \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \ = \sf\frac{3xa}{5 {y}^{3} b} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \ = \sf 3xa \ratio 5 {y}^{3} b$

Thanks ..!!
