Hi
I am not a micro expert but can somebody tell me how many 0' are in
5x106
5x102
Is there a chart to help me with this?
Cheers

if you have excel you can perform exponents by using the ^ symbol. For example go into a cell and put =5*10^6 and hit enter

Dear astro,
I assume this is a "micro" question.
Yr query refers to "multiplying whole numbers by powers of ten".
I assume you only have whole numbers, eg 1,2,3,4 and not numbers in decimal format, eg 1.1, 2.2, etc.
In yr OP example 5x106, the number after the "10" is called "the exponent", ie exponent = 6
The solution to yr OP is according to this rule -
Add as many zeroes to the right of the whole number as the exponent.
so, for 5x106, add 6 zeroes > 5,000,000
similarly for 5x102, exponent is 2, > 500
Note again, this method fails if the number has a decimal format, eg 5.1x106 will not work as per this rule (see link below).
The reason why the rule works is explained here -

(see No.1 for whole numbers, No.2 for decimals)

This is Maths not micro (as per Charles' link 'Add on as many 0's as appear in the power') so where N is a number between 1 and 9:
Nx100 = No Zeros = N
Nx101 = 1 zero = N0
Nx102 = 2 Zeros = N00
Nx103 = 3 Zeros = N,000
Nx104 = 4 Zeros = N0,000
Nx105 = 5 Zeros = N00,000
Nx106 = 6 Zeros = N,000,000
Nx107 = 7 Zeros = N0,000,000

Thanks guys for your expertise feed back that is most useful.
One more for you if you may
<300 / g (2)
m 500 / g - M 5000 / g ; n=5 et c = 2 (2)
abs / 25g (1) which normally i understand abs in 25g or present in over 25g

Dear Astro,
Maybe you should tell us how much maths you understand ?
eg
(i) < = ?
(ii) 10x = ?
(iii) "(2)" as in 2(2) = ?
(iv) "(1)" as in 25g(1) = ?
the definition of m,M,n,c is easy, straight from a textbook.
But the understanding of the definitions is likely outside your scope if you do not know the answers to (i-iv) above.

I know enough to get by THANKYOU
This still did not answer the question
All I'm after is what the number in the bracket represents??

Hi astro
to answer your query
class sampling plans consist of
n – number of sample units to be chosen independently and randomly from the lot
m – a microbiological limit that separates good quality from marginally acceptable quality
M – a microbiological limit above which sampling results are unacceptable or defective
c – maximum allowable number of sample units yielding results between m and M (marginally acceptable);
the number of sample units allowed to exceed M is usually set to 0

Simples!
It is to some people but like a foreign language to others
I'm always thankful that I have always excelled at Maths as it helps so much in real life and you are less likely to be ripped off.
