The option that expresses the age of tree in scientific notation with the lowest level of precision would be A. 3 X 10 to the 3rd power. As it contains the fewest number of significant figures.

Answer: \(3.2\times 10^3\)

Step-by-step explanation:

In scientific notation, a given number is written as the product of two numbers, a coefficient and 10 raised to a power.

When written in standard form there must be one digit to the left of the decimal point in the coefficient.

\(N\times 10^n\)

N= coefficient

n= power, can be positive or negative

Precision of a number refers to the decimal position of the significant digit furthest to the right. The number with more number of significant digits is more precise.

Thus \(3.2\times 10^3\) is the least precise and written in scientific notation.
