A) \[x=\sqrt{y}\]
B) \[x={{y}^{3}}\]
C) \[y={{x}^{2}}\]
D) \[x={{y}^{2}}\]
Correct Answer: D
Solution :
(d) (i) use the identity \[\frac{\log a}{\log b}=\text{ }lo{{g}_{b}}a\] (ii) \[\frac{\log x}{\log y}=2\Rightarrow lo{{g}_{y}}x=2\] (iii) \[lo{{g}_{b}}a=n\Rightarrow a={{b}^{n}}\]You need to login to perform this action.
