Can someone explain how the answer is 33?

120 (r-2)^2 + (r-9)^2 = r^2 r = 17 or 5 But if r = 5, r-9 will be negative So r = 17 So (17-2)(17-9) = 120
No, because a perfect square doesn't end in 2 or 7

I was kinda start to understand it now I am back to 0 😂
n = 45, p = 2
Didn't get it. From one of your replies, I see it has something to do with prime numbers. Totally forgotten what a prime number even is. 😄 Guess I'd better go & look it up. 😄😄

A simple idea is to complete te square on the left. So first we multiply by 4. We get 4x²+20x+12=4y² Now (2x+5)²-13=4y² (2x+5)²-(2y)²=13 (2x+2y+5)(2x-2y+5)=13 Assuming x,y are positive integers we can conclude 2x+2y+5≥9 so 2x+2y+5=13 and 2x-2y+5=1from which its easy to see that the only solution is {1;3}.
Absolutely right 🙂
Very nice

Actually the answer is 3,5,11 which are the prime factors of 165 in ascending order
1,5 is not equal to 1×0,5 Its 3×0,5 not 1×0,5
I agree. Never wrote that :)
Yeah I'm still asking myself why i needed to learn this shit in high school
That´s a good question. You try hard to learn all these things , they told you that you ll have a better life if you are an educated man and then you realize that some f*ckin politicians take decisions for your future without asking you ...
Je sure it's EZ
yep 🙂
with log you mean ln ? Else its great !
Log means base 10, ln stands for natural log which is base (the constant of e). You're not wrong, both work for this problem!
In most text books log without any reference at logs base means log base 10. Wolfram Alpha take log(x) as ln(x) and that causes some confusion. What ever you write ( log with any base or without base or ln ) the answer in the equation above remains the same.
