Answer 1:
No, you can divide it by 5.
8000002+10000000+3 = 18000005
18000005 is divisible by 5
Answer 2:
I do not understand the above answer. It seems to me that the question itself does not provide enough information to answer.
What is the value of "m"? Does the "2" in "8m2" represent that we are to square the product of "8" and "m"?
Or is there a standard value of "m" that I am unaware of, or is it just taken to mean "meters" and thus is irrelevant to the equation?
But if it is for "meters", then 16 plus 10 plus 3 is 29 and that is a Prime number, and cannot be divided by 5.
The first person answering seems to be making the assumption that the "m" stands for "million", and that 8m2 therefore means 8,000,002, and the 10m means 10,000,000. I am unaware of such a means of notation. Even if one took "m" to be 1,000,000 then the customary way of showing 8,000,002 would be 8.000002m, not 8m2.
10m + 3
When n = 1, 2, 3, 4, the result is not prime.
It is may be prime only if one term is 2. for example: 3+2=5But one term may be 2 and the result composite: 7+2=9=3*3
It is: 3 plus 97 = 100
5, 7, 11, 13, 17, and 19; plus 3 if you are including it.
Nothing because 31 is a prime number
Amount of HCl is 500cm^3 of .8M HCl = .8 x 500/1000 = 0.4 mol. Volume of 10M acid to give 0.4 mol = .4/10 = 0.04dm^3 = 40cm^3 Add 500 - 40 = 460 cm^3 of water. Caution : 10M HCl is highly corrosive and should be handled with care.
22 + 3 = 7 Since 2 is the only even prime number, this is the only number for which this holds true.
The number 27 has a cube root of 3, which is 2 (the smallest prime) plus 1.
2 + 3 = 5 Two plus any odd prime number is odd.
Composite. It is divisible by 3 for any n.
No. It factors to (11x - 13)(2x - 3)
