Answer:

The age of the tree in scientific notation form is
3.212* 10^(3) .

Option (D) is correct .

Explanation:

As given in the question

A tree is 3,212 years old.

Now write 3212 in the scientific notation form .

= 3212

Multiply and divided the above expression by 1000 .


= (3212* 1000)/(1000)

Simplify the above


= (3.212)/(1000)

Thus it is written as


= 3.212* 10^(3)

Therefore the age of the tree in scientific notation form is
3.212* 10^(3) .

Option (D) is correct .

Lowest precision means the least number of significant figures are taken and the error is greatest.
