Question

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.

Answer 1

3 to the 2 over 3 power inches squared
3 to the 8 over 3 power inches squared
9 inches squared
9 to the 2 over 3 power inches squared

Answer 2

area = length * width
= 81 ^ (1/3) * 3 ^(2/3)

Answer 3

is that correct?

Answer 4

yes thank you very much i first i thought it was 3^ 8/3

Answer 5

well you need to make the base number = 3

81 = 3^4

so 81^(1/3) = 3^(4/3

so we have

3^4/3 * 3 ^ 2/3

now you add the powers

= 3 ^ 6/3 = 3^2

Answer 6

thats it
