You multiply 4*16= 64. Then you take square root of 64. 8 is your answer.
4-3 = 1/64
x^3 = 64 x = 64^(1/3) or 64^(0.33333......) x = 4 By reverse argument 4 x 4 x 4 = 16 x 4 = 64
25, 36, 49, 64
16 x 4 = 64The product is 64
You multiply 4*16= 64. Then you take square root of 64. 8 is your answer.
you find out what 64times64times64 is. did you mean waht cubed equals 4? that answer is 4(4x4x4=64)
If by area you mean volumethe cuberoot of 64 = 4.If you mean the surface arearoot (64/6) = 3.266
It is 64.
√64 x √16 = 8 x 4 = 32
4-3 = 1/64
(4 x 20) - 16 = 43 Check: 80 - 16 = 64 64 = 64
If you mean an equilateral cube (all sides same length, etc), then it would be the cube root of 64 = 4. (4*4*4 = 64). So the height = 4 feet.
I would let "direct" mean "linear." The answer then becomes simpler; direct proportional may mean a relationship like 1-1, 2-2, 3-3, etcetera. Proportional by itself would then be free to indicate other proportions; like 1-1, 2-4, 3-9, etcetera -- in an exponential proportion.
4
If you mean 64 and 16 then it is 4 to 1
mary with 4 and 8
