Atree is 3, 212 years old. how can you express this age in scientific notation with the lowest level of precision. a. 3x10 to the 3 power b. 3.2 x 10 to the 3 power c. 3.21x 10 to the third power d. 3.212x 10 to the 3 power

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= 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 is the least precise and written in scientific notation.

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
