Evaluate the following (i) `(3sqrt64)^((-1)/2)" "(ii) (121/169)^(-3//2)` |
|
Answer» (i) `(3sqrt64)^((-1)/2)=[(64)^(1/3)]^((-1)/2)=(64)^(1/3xx(-1)/2)=(64)^((-1)/6)` `=(2^(6))^((-1)/6)=2^(6xx((-1)/6))=2^(-1)=1/2` (ii) `((11xx11)/(13xx13))^(-3//2)=(11^(2)/13^(2))^(-3//2)=(11/13)^(2xx(-3)/2)=(11/13)^(-3)=(11/13)^(3)=2197/1331` |
