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.

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
