the distance from earth to proxima centauri is expressed in scientific as 4.0208 × 10¹³ kilometers.

Explanation:

First Question:

The method to express very large or small numbers concisely is scientific notation, as it represents numbers as \( a \times 10^n \) where \( 1 \leq a < 10 \) and \( n \) is an integer.

In scientific notation \( a \times 10^n \), the \( a \) (with \( 1 \leq a < 10 \)) is called the coefficient (or mantissa).

In scientific notation \( a \times 10^n \), the base of the power is 10, so the exponent indicates how many times 10 is multiplied or divided.

Answer:

scientific notation
