27
(2/3)³
= 2 • 2 •2 / 3 • 3 • 3
= 8/27
2/3 times 2/3 times 2/3 = 8/27 (multiplying the numerators together and dividing by the product of the denominators)
cube the top. cube the bottom.
done
(â
)³ = (2³) ÷ (3³)
= 8 ÷ 27
= 8/27
whenever theres a question that i can actually answer there are like 20 people already on it lol
The cube of 2/3 is the cube of 2 divided by the cube of 3=8/27.
(2/3)^3
= 2/3 x 2/3 x 2/3
= (2 x 2 x 2)/(3 x 3 x 3)
= (4 x 2)/(9 x 3)
= 8/27
