79 x 1 39.5 x 2

The formula would be: X(X+1)=6162. X^2+X = 6162. X^2+X-6162 = 0; Factor this. (X+79)(X-78)=0. X+79=0 or X=-79; impossible. X-78=0; X=78; first page. Second page X+1=79. Therefore page numbers are 78 & 79. Check: 78*79=6162.

To find 2 percent of a number, multiply the number by 0.02. In this instance, 0.02 x 79 = 1.58. Therefore, 2 percent of 79 is equal to 1.58.

In the prime factorisation of a perfect square in power format, all primes must be to an even power. 5688 = 23 x 32 x 79 To convert this it a perfect square, it needs the 2 and 79 to have an even power - the 3 is already at an even power. The smallest way to do this is to multiply 5688 by 2 x 79, ie multiply it by 158. 5688 x 158 = 23 x 32 x 79 x 2 x 79 = 24 x 32 x 792 = (22 x 3 x 79)2 = (948)2 = 898704

1/2 x 158 = 79

1 x 474, 2 x 237, 3 x 158, 6 x 79, 79 x 6 = 474
