Correct Answer: B
Solution :
(b); \[{{\left( \frac{5}{3} \right)}^{-5}}\times {{\left( \frac{5}{3} \right)}^{-11}}={{\left( \frac{5}{3} \right)}^{8x}}\] \[\Rightarrow {{\left( \frac{5}{3} \right)}^{-5-11}}={{\left( \frac{5}{3} \right)}^{8x}}\] \[\Rightarrow -5-11=8x\]You need to login to perform this action.
