cubic millimeters. It's a (fairly small, by normal everyday standards) unit of volume, equivalent to one microliter.
It is 5 cm.
8 to the third power is 8x8x8=512
It means 3 to the third power
To find the diameter of the field of view at high power, you can use the height of the field. If the field is 1.2 mm high and the object occupies one third of that field, then the height of the object is 0.4 mm (1.2 mm / 3). The diameter of the field of view is equal to the height when viewed in a circular field, so it remains 1.2 mm.
In exponents cubed means "to the third power"5 Cubed =5 To the third power =53 =15
If you mean 27 to the power of 2/3 then it is 9
A third of A4 refers to a paper size that is one-third the dimensions of an A4 sheet, which measures 210 mm x 297 mm (8.27 in x 11.69 in). Thus, a third of A4 would be approximately 210 mm x 99 mm (8.27 in x 3.9 in). This size is often used for brochures or flyers.
It means 4 to the third power
If you mean: 2^3 times 2^7 times 2^3 then it equals 8192
It might mean "9 cm 8 mm"
It means multiplied by itself three times. For example, two to the third power (23) is 2 x 2 x 2, which equals 8.
MM = 2000
