A) \[{{p}^{3}}{{q}^{4}}{{r}^{7}}\]
B) \[{{p}^{3}}{{q}^{4}}{{r}^{10}}\]
C) \[{{p}^{-9}}{{q}^{2}}{{r}^{-4}}\]
D) \[{{p}^{9}}{{q}^{-2}}{{r}^{4}}\]
Correct Answer: D
Solution :
\[\frac{{{p}^{4}}{{q}^{3}}\times {{p}^{2}}{{r}^{4}}\times {{q}^{-2}}{{r}^{3}}}{{{p}^{-3}}\,{{q}^{3}}\,{{r}^{3}}}\]\[={{p}^{9}}\,\,{{q}^{-2}}\,\,{{r}^{4}}\]You need to login to perform this action.
