A) \[{{b}^{2}}{{x}^{4}}{{a}^{6}}z\]
B) \[{{b}^{3}}{{x}^{2}}{{a}^{4}}{{z}^{3}}\]
C) \[{{b}^{3}}{{x}^{5}}{{a}^{5}}{{z}^{2}}\]
D) \[{{b}^{3}}{{a}^{5}}{{z}^{2}}\]
Correct Answer: C
Solution :
Expression \[=\frac{{{b}^{3}}{{x}^{2}}{{a}^{4}}{{z}^{3}}\times {{b}^{4}}{{x}^{3}}{{a}^{3}}{{z}^{2}}}{{{a}^{2}}{{b}^{4}}{{z}^{3}}}\] \[=\frac{{{b}^{7}}{{x}^{5}}{{a}^{7}}{{z}^{5}}}{{{a}^{2}}{{b}^{4}}{{z}^{3}}}\] \[{{b}^{7-4}}{{x}^{5}}{{a}^{7-2}}{{z}^{5-3}}\] \[={{b}^{3}}{{x}^{5}}{{a}^{5}}{{z}^{2}}\]
