## pandaecat one year ago A rectangle has a length of the cube root of 81 inches and a width of 3 to the 2 over 3 power inches. Find the area of the rectangle. A 3 to the 2 over 3 power inches squared B 3 to the 8 over 3 power inches squared C 9 inches squared D9 to the 2 over 3 power inches squared I think it's C but I'm not really sure. Can someone explain to me?

1. anonymous

the formula for area is length x width

2. pandaecat

@egbeach I know that... but I just don't get how u simply the thing

3. anonymous

$\sqrt[3]{81} \times 3^{\frac{ 2 }{ 3 }}$

4. anonymous

thats the equation right?

5. pandaecat

Yes

6. anonymous

well whats $\sqrt[3]{81}$

7. pandaecat

81 and one third

8. anonymous

$81^{\frac{ 1 }{ 3}}\times 3^{\frac{ 2 }{ 3}}$

9. anonymous

are you able to solve that?

10. pandaecat

Um er a moment

11. anonymous

it should work if you plug it into a calculator correctly

12. pandaecat
