Question

Find sub-triplicate ratio of :

$\left(ii\right)$ $x^3:125y^3$

Answer 1

Step: Find sub-triplicate ratio

Sub-triplicate ratio is the ratio between the cube roots of the two numbers.

Sub-triplicate ratio $=\sqrt[3]{3x^3}:\sqrt[3]{3125y^3}$

$=\sqrt[3]{3x^3}:\sqrt[3]{3(5y{)}^3}$

$=x:5y$

Hence, the sub-triplicate ratio is $x:5y$
