A) \[{{(rqs)}^{-1}}\]
B) \[0\]
C) \[1\]
D) \[r+q+s\]
Correct Answer: C
Solution :
\[{{q}^{-a}}=\frac{1}{r},\,\,r={{q}^{a}}\] ??(i) \[{{r}^{-b}}=\frac{1}{s},\,\,s={{r}^{b}}\] ??(ii) \[{{s}^{-c}}=\frac{1}{q},\,\,q={{s}^{c}}\] ??(iii) From equation (iii) - \[q={{s}^{c}}\] \[q={{({{r}^{b}})}^{c}}\] \[q={{r}^{b}}^{c}\] \[q={{({{q}^{a}})}^{bc}}\] \[q={{q}^{abc}}\] So, abc= 1You need to login to perform this action.
