Sorry I'm dum,b and don't know scientific notation very well please explain for brainly =D

Sagot :

The simplest I can put it

10^1 = 10
10^2 = 100
10^3 = 1000
(essentially the number of zeroes)

5*10^2 = 5*100 = 500 (adding 2 zeroes, or moving the decimal over 2 places

Same works for numbers smaller than zero

5*10^-2 = 5*.01 = .05 (moving the decimal to the right 2 places

Answer:

Step-by-step explanation:

How did  you miss this?     it's just about moving the decimal place to where it makes better sense.  which just means, it's easier to read, and maybe to compare with other numbers.    Like how maybe

1,000,000,000,000  might be harder to compare to 1,000,000,000,000,000 than if it looked like this in scientific notation

1.0 x[tex]10^{12}[/tex]   and

1.0 x[tex]10^{15}[/tex]

right away you can see the difference, right?

the lower two numbers are the same as the upper two numbers ,  just to be clear.

also, if the number is much messier  like this

2,254.2356111142254  then it's good to put into scientific notation as

2.254 x [tex]10^{3}[/tex]

scientific notation always puts the decimal after the very 1st digit never like this

22.54 x[tex]10^{2}[/tex]

that's not correct scientific notation.  The decimal always goes right after the 1st digit like this

3.00 x[tex]10^{8}[/tex]  Km/s  maybe you'll recognize this as a very close approximate  for the speed of light?      anyway, hope that helps
