a is 3m
b is 3n
m and n are relatively prime - they do not have any common factors.
a2 = 9m2
Since m had no factors in common with n, m2 also has no factors in common with n. We know that 3 is a common factor of a and b. The only new possible factor between a2 and b is the second 3 when a is squared. We do not know whether b had more than one factor of 3. So, the greatest common factor of a2 and b, when the greatest common factor of a and b is 3, is either 3 or 9.

You can use if-else statements to check for equality.Eg:
char a, b, c;
scanf("%c%c%c", &a, &b, &c);
if( a==b && b==c)
printf("They are equal\n");
else
printf("They are not equal\n");

In algebra this is a method of solving equations for a variable. It stands to reason that if A=B then A+1=B+1. In fact it is true that if N is a number then
A+N=B+N
A-N=B-N
A x N = B x N
A/N = B/N
We can do anything we want as long as we do the same thing to both sides.

Thing is, 3 doesn't equal 0.03...
But... using false logic,
it could be proved:
Do we agree:
0/3 = 0/0.03 = 0
We know if:
n/a = n/b
then, a =b.
Therefore, 3 = 0.03
However, you can't do that with a 0, so
3 doesn't equal 0.03

n= 2B2-B
B= y-1
Substitute.
n=2(y-1)2-(y-1)
Foil (y-1)2.
n=2(y2-2y+1)-(y-1)
Distribute the 2.
n=2y2-4y+2-(y-1)
Distribute the negative.
n=2y2-4y+2-y+1
Combine like terms.
n=2y2-5y+3
Final answer:
n=2y2-5y+3

If a divides b then a is a factor of b and b is a multiple of a.
Either of them could be the denominator. In a/b, b is the denominator while in b/a, a is the denominator.

If a divides b then b=n*a for some number n. Thus n=b/a

you use loops to draw out information from an array or a vector. Also they can be used to count up or down from any giving number.
#include <iostream>
using namespace std;
int main()
{
short a = 1;
short b = 1;
short c = 2;
//do
while (a && b && c != 34);
{
a = c + b;
cout << a << "\n";
b = a + c;
cout << b << "\n";
c = b + a;
cout << c << "\n";
}//while (a && b && c != 34);
return 0;
}
the output of this program would be
3
5
8
13
21
34
if i was to rewrite this program with out the loop, i would have to write the body of the loop
a = c + b;
cout << a << "\n";
b = a + c;
cout << b << "\n";
c = b + a;
cout << c << "\n";
over and over again until i reached the number 34. its adding 1 + 1 = 2
2+1=3, 3+2=5 and so on, that's how the program is reaching 34.

It is not simple. The only systematic way is to find the prime factorisation of the number and write it in exponential form.
So suppose n = (p1^r1)*(p2^r2)*...*(pk^rk) where p1, p2, ... pk are prime numbers and rk are the indices (or powers).
Then the factors of n are (p1^s1)*(p2^s2)*...*(pk^sk) where 0 ≤ sk ≤ rk. And remember that anything raised to the power 0 is 1.
Example:
n = 72 = 2*2*2*3*3 = (2^3)*(3^2)
so, the factors of n are (2^a)*(3^b) where a = 0, 1, 2 or 3 and b = 0, 1 or 2.
When
(a, b) = (0, 0) the factor is 1.
(a, b) = (1, 0) the factor is 2.
(a, b) = (2, 0) the factor is 4.
(a, b) = (3, 0) the factor is 8.
(a, b) = (0, 1) the factor is 3.
(a, b) = (1, 1) the factor is 6.
(a, b) = (2, 1) the factor is 12.
(a, b) = (3, 1) the factor is 24.
(a, b) = (0, 2) the factor is 9.
(a, b) = (1, 2) the factor is 18.
(a, b) = (2, 2) the factor is 36.
(a, b) = (3, 2) the factor is 72.

Yes, here's how you can show it, for the equivalent proportions a/b & (n*a)/(n*b):

Cross multiply: a*n*b ? b*n*a. Because multiplication is commutative, the question mark is an equal sign.

The remainder is 0.
If A has a remainder of 1 when divided by 3, then A = 3m + 1 for some integer m
If B has a remainder of 2 when divided by 3, then B = 3n + 1 for some integer n
→ A + B = (3m + 1) + (3n + 2)
= 3m + 3n + 1 + 2
= 3m + 3n + 3
= 3(m + n + 1)
= 3k where k = m + n + 1 and is an integer
→ A + B = 3k + 0
→ remainder when A + B divided by 3 is 0

The rate law for this reaction is rate = k[A]^m[B]^n. From the given information, substituting the values for rate, [A], [B], and the exponents m and n, you can solve for the rate constant k. In this case, k = rate / ([A]^m[B]^n), so k = 2 / (10^2 * 3^1).
