A prime number times a prime number is a composite number. Since prime numbers, except for 2, are odd numbers, a prime number times a prime number is usually an odd number. It will only be an even number if one of the prime numbers is 2. A prime number times a prime number will be a number with four factors unless both prime numbers are the same, in which case it will be a square number with only three factors.
101 is a prime number. The only factor of 101 is itself and 1.prime

No. If the two numbers are consecutive then the difference of their squares need not be factorisable. For example, 4^3 - 3^3 = 16 - 9 = 7, which is a prime. If the smaller number is a then this simply requires that 2a+1 is a prime.

20 = 1Consider what is the value of 2a ÷ 2a? Any number divided by itself is 1. Thus:2a ÷ 2a = 1The law of indices says that when dividing, they are subtracted, for example:25 ÷ 22 = (2 x 2 x 2 x 2 x 2) ÷ (2 x 2) = 2 x 2 x 2 = 23 = 25-2So 2a ÷ 2a is (also):2a ÷ 2a = 2a-a = 20Since any number subtracted from itself is 0 (= a - a). This must have the same value as before, thus:20 = 1The 2 above can be replaced by any number x which means that any number to the power 0 is 1:x0 = 1
A + 2a = 3a
As all the required numbers are even, we can identify the smallest value number as 2a, then the other three consecutive even numbers are (2a + 2), (2a + 4) and (2a + 6). The sum of these four numbers is, 2a + (2a + 2) + (2a + 4) + (2a + 6) = 8a + 12 Then, 8a + 12 = 412 8a = 412 - 12 = 400 2a = 400 / 4 = 100 The four consecutive even numbers are 100, 102, 104 & 106. NOTE : In this problem the choice of 'a' as the smallest value number would have achieved the correct answer but in other situations such a choice could have resulted in 4 consecutive ODD numbers being found. When in doubt use 2a or similar to clearly identify that the number is even.
The answer really depends on what number you are doubling. Let's say that you wish to double the number a (which we assume is greater than 0). If we're raising a to the nth power, then n must satisfy the following equation: an = 2a Taking the natural log on both sides, n log a = log (2a), n = log (2a) / log a. So if we double the number a, it is raised to the log (2a) / log a power.

i think yes, because you can combine 2 and -2, which are like terms, so why not 2a and -2a?
You don't have a number alone. Also I'll make the assumption that it is 19a+2a-4a+3a Without a number alone, it can't really be solved, unless a=0 19a+2a-4a+3a can be simplified however to 20a
9a +8 -2a -3 -5a = 2a +5
