2/3 x 81 = 54
(2/3) x (2/3) x (2/3) x (2/3) = (2/3)4 = 16/81
81 times 2 cubed is equal to 648.
negative two-thirds
7.5 divided by 2 2/3 is 2.81 or 2 81/100
You can express 81 as a power in several ways: ( 81 = 3^4 ) because ( 3 \times 3 \times 3 \times 3 = 81 ). ( 81 = 9^2 ) since ( 9 \times 9 = 81 ) and ( 9 ) can be rewritten as ( 3^2 ). ( 81 = (3^2)^2 ) which simplifies to ( 3^{2 \times 2} = 3^4 ). Thus, all representations confirm that ( 81 ) can be expressed as a power in different forms.
(2/3) x (2/3) x (2/3) x (2/3) = (2/3)4 = 16/81
2/3 of 81 = 54
81 times 2 cubed is equal to 648.
negative two-thirds
2 of them times 4 is 8, so 8 thirds = 8/3 = 2 and 2/3
51/2 times
7.5 divided by 2 2/3 is 2.81 or 2 81/100
4 over 9 (fraction)
82/3 = (81/3)2 = 22 = 4
If the person is two-thirds of their father's height and is 54 inches tall, we can set up the equation: ( \frac{2}{3} \times \text{father's height} = 54 ). To find the father's height, we can rearrange the equation: ( \text{father's height} = 54 \div \frac{2}{3} = 54 \times \frac{3}{2} = 81 ) inches. Therefore, the dad is 81 inches tall.
4 2/3 x 1/2 is 2 1/3
2 times 2/3 = 4/3
