Question

PLEASE HELP ASAP!!!!

1. A tree is 3,212 years old. How can you express this age in scientific notation with the lowest level of precision?

A. 3*10^3
B. 3.2*10^3
C. 3.21*10^3
D. 3.212*10^3

THANKS!

Answer 1

I think the answer is A, but not entirely sure.

Answer 2

ur right nice goin :))

Answer 3

Thanks! Does anyone disagree?

Answer 4

::))) ur frree to close question ehehhe

Answer 5

I think its B

Answer 6

i mean D

Answer 7

ur wrong try counting up

Answer 8

First, we will put a decimal point at the end of number 3212.
In order to write number 3212. in scientific notation we need to move the decimal point from its current location (black dot) to the new position (red dot).
3.212.
So, we need to move decimal point 3 places to the right.
This means that the power of 10 will be positive 3.
Now we have that the
Number part = 3.212 and
Exponent part = 3

Answer 9

I was considering both but don't know. I guess I'll go with A.

Answer 10

In which i got 3.212⋅10^3

Answer 11

go on its your choice :D ill fann u sky

Answer 12

Thanks! The only thing that confuses me is the "lowest level of precision"

Answer 13

What exactly does that mean? Would that mean the choice that is farthest from the actual answer, like A.?

Answer 14

mmmm C

Answer 15

D would be the most precise answer, wouldn't it?

Answer 16

yah it would

Answer 17

So A. would be the least precise answer of the four options?

Answer 18

D

Answer 19

How would it be D @sws_pvt

Answer 20

Yes it would be D like i said

Answer 21

The only thing that I don't understand is that it seems like D. is the most precise answer of the four, not the least.

Answer 22

@skysrv if you think about it, all of the numbers have to all ready be there. they aren't just appearing. All the numbers have to all ready be there before scientific notation.

Answer 23

But at the end of all this, wouldn't it be the most precise answer though?

Answer 24

THis will help you understand better

Answer 25

Oh, okay, I think I understand.

Answer 26

Just submitted it, the answer was A.

Answer 27

But, thanks for your help! I better understand scientific notation, so thanks!
