##### A Few Questions

Hi Brent, I have a few questions, so I start with the first one. In the video 38 of Integer Properties module, we have a DS q. You don't rule out the first statement because you say 5J should have prime factorization of 5*?*?*?*?, and 3k should have prime factorization of 3*?*?*?*?. And since the fi...

Thank you so much, Brian. Your explanation couldn't get clearer. I just wrote down what you said in my Verbal notebook so that I wouldn't forget it later on. Thanks a lot, again.

First of all, on the OG13, it doesn't say, "age, in which" and "a time, when". It says, "an age in which" and "a time when". Please refer to the mentioned questions on my post. Then, isn't 'an age' also 'a time'? So, if we can say, "an age in which",...

##### OG13 SC Q35 VS. Q72

Actually, your way of solving this question is quite correct ....and after all, it's such a simple question. I don't know why I was trying to sophisticate the problem and came here and asked those stupid embarrassing questions that have nothing to do with this easy question at all

Hi, Using the combination formula, we will know how many groupings of 2 of these 4 expression we can have:4!/(4-2)!2!=6 So, now, let's see how many of these 6 combinations are of the form of (x^2)-[(by)^2], which is (x+by)(x-by)... (x+y)(x+5y): it's not of the form of (x+by)(x-by), so NO (x+y)(x-y):...

Thank you so much, Dabral. I just checked your fabulous website...and bookmarked it right away. And thank you for that attached image of your explanation too.

You end up buying a pair of jeans for $20. Then, the very next day, you go to this cloths store again and decide to...
