Evaluate each of the following :
`(i)(sqrt(9))^(-3)" "(ii)(3sqrt(8))^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
N/a
(i) `(sqrt(9))^(-3)=(9^(1//2))^(-3)=9^((-3)/(2))=(3^(2))^(-(3)/(2))=3^(2xx(-(3)/(2))=3^(-3))=(1)/(3^(3))=(1)/(27)`
(i) `(3sqrt(9))^(-2)=(8^(1/(3)))^(-2)=8^(-(2)/(3))=(2^(3))^(-(2)/(3))=2^(3xx(-(2)/(3))=2^(-2))=(1)/(2^(2))=(1)/(4)`
