Correct Answer: C
Solution :
(P) \[\left[ {{\left( {{5}^{3}} \right)}^{2}}\times {{5}^{5}} \right]\div {{5}^{9}}=\left( {{5}^{6}}\times {{5}^{5}} \right)\div {{5}^{9}}\] \[=({{5}^{6+5}})\div {{5}^{9}}={{5}^{2}}=25\] (Q) \[{{(-6)}^{5}}\div {{(6)}^{2}}={{(-1)}^{5}}\times {{(6)}^{5}}\div {{(6)}^{2}}\] \[=(-1)\times ({{6}^{5-2}})={{(-1)}^{3}}\times {{6}^{3}}=-{{(-6)}^{3}}\] (R) \[({{5}^{0}}+{{3}^{0}})\div ({{8}^{0}})=(1+1)\div (1)=2\] (S) \[{{\left( \frac{7}{19} \right)}^{0}}=2\]You need to login to perform this action.
