Question

0.002м^2 что значит ^

Answer 1

Скорей всего это знак степени.
Т.е.   10 м^2 - читается как десять квадратных метров метров 

Answer 2

In mathematics, the symbol "^" denotes exponentiation. When you see a number or a variable followed by the "^" symbol and another number or variable, it means raising the base number (or variable) to the power of the exponent. For example:

• 2^3 means "2 raised to the power of 3," which is equal to 2 x 2 x 2 = 8.
• x^2 means "x raised to the power of 2," which represents x multiplied by itself: x * x.

In your specific case, "0.002м^2" means "0.002 square meters." It indicates an area measurement of 0.002 square meters. The "^2" in this context refers to the unit of area, which is meters squared (m^2).
