Hi, I really need help at umm prime factorization....uhh i think its like using exponents, so yeah... 36 , 81 , 65 , 19 , 24 , 18 , 40 , 75 , 27 , 32 , 49 , 25 , 42 , 104 , 55 , and 77

2. Here's an example, I will keep reducing my factors until they are prime. Once this is done I put them into index form

$36 = 6\times 6 = (3\times 2)\times (3 \times 2) = 3^2\times 2^2$

Index form works as follows

$a\times a = a^2$

$a\times a \times a = a^3$

$a\times a \times a \times a= a^4$

and so on...

im really stupid....i dont really get what you mean...i just moved in USA 3 years....P.S. ME AZN (Asian)

4. which bit could you follow? do you know the multiplication tables?

yes....I know that...... i need help with prime factorization using exponents

6. My first post in this thread is doing exactly what you are after, study it.

Here is another example

$81 = 9\times 9 = (3\times 3) \times (3\times 3) = 3^4$

I made 81 into factors of 9, then the 9s into factors of 3.

As I had $(3\times 3) \times (3\times 3)$ I could say that was $3^4$
