Evaluate (2/5) ^4
To evaluate (2/5)^4, we need to raise 2/5 to the fourth power.
(2/5)^4 = (2/5) * (2/5) * (2/5) * (2/5) = 16/625
Therefore, (2/5)^4 is equal to 16/625.
Use the formula s^3 to find the volume of a cube when s represents the length of a side of the cube. Find the volume of a cube if the side length is 3/5 feet.
To find the volume of a cube, we use the formula V = s^3, where s represents the length of a side of the cube.
Given that the side length is 3/5 feet, we substitute this value into the formula:
V = (3/5)^3 = (3^3) / (5^3) = 27 / 125
Therefore, the volume of the cube with a side length of 3/5 feet is 27/125 cubic feet.
Use the formula s^2 to find the area of a square when s is equal to one side length of the square. Find the area of a square that has a side length of 8/15 mm.
To find the area of a square, we use the formula A = s^2, where s represents the length of a side of the square.
Given that the side length is 8/15 mm, we substitute this value into the formula:
A = (8/15)^2 = (8^2) / (15^2) = 64 / 225
Therefore, the area of the square with a side length of 8/15 mm is 64/225 square mm.
The area of a square room is found by multiplying the length times the width. Evaluate the power to find the area of the room if the length and width of the room are 13 feet.
To find the area of a square room, we multiply the length of the room by its width.
Given that the length and width of the room are both 13 feet, we can calculate the area:
Area = length * width = 13 feet * 13 feet = 169 square feet
Therefore, the area of the room is 169 square feet.
