Answer 1

1) пред. абс. погр. ∆=0.01, относит. Е=∆/а=0.01/2.15≈0.0047=0.47%
2) 2.235*10^-1; 5*10^-4; 5*10^4
4) 32.2≤а≤33.2

Answer 2

The symbol Δ usually represents the uncertainty or absolute error of a measurement. In this case, it seems like you have provided the value of "a" along with its uncertainty, but you haven't specified what type of measurement it is.

Similarly, the symbol E usually represents the experimental error or relative error of a measurement, but again, without more context, it's difficult to provide a specific answer.

It's unclear what you're asking for in the second question. "22.35", "0.0005", and "50000" seem to be three separate values with no context. Please provide more information or context so that I can help you.

The symbol ± represents the uncertainty or error of a measurement. In this case, you have provided the value of "a" as 2.5 with an uncertainty of 0.344. This means that the true value of "a" is somewhere between 2.156 and 2.844 (i.e., 2.5 ± 0.344).

For the measurement of "a" with a value of 32.7 and an uncertainty of 0.5, the range of possible values for "a" is between 32.2 and 33.2 (i.e., 32.7 ± 0.5).
