Best ResponseYou've already chosen the best response.01. area of rectangle is the length l times the width w 2. length l is cube root of 81 and the 3 ^(2/3) and be simplified to cuberoot((3^2) which is cube root of 9. now they have the same power. 3. (81^(1/3))*(9^(1/3)) is (729^(1/3)) by the exponential law. 4. Using a calculator or your head you get that the cube root of 729 is simply 9.
