Please everyone, after I found the value of 'a', I mistakenly switched the sign from + to -. Am so sorry, kindly ignore the switch and keep on solving with the +, the solution wasn't affected.
JJ you are doing a great job. But please check your solution again. Please make the correction in another video. Somewhere after you had your value of a you switch your signs from + to - .
Hi JJ how you come transition from 1 - 2 raised,c /2raised b = 9 to 2raised to c / 2 raised b = 8. ????? You supposed to have - (2 raised to c/ 2 raised to b )= 8 So what happened to your minus sign in front of 2raised to c/ 2 raised b ??????

Without conditions the problem will have multiple solutions. Put a
CONGRATS ❗ Nice démonstration based on mathematical laws.
The explanation is clear❗
Thanks so much
Amazing
Thanks so much
That is what was puzzling me , how + changed to - with no clear explanation but not satisfied, thanks for that wonderful lecture
GREAT JOB SISTER
2^(a) + 2^(b) + 2^(c) = 148
2^(a) + 2^(a + b - a) + 2^(a + c - a) = 148
2^(a) + [2^(a) * 2^(b - a)] + [2^(a) * 2^(c - a)] = 148
2^(a) * [1 + 2^(b - a) + 2^(c - a)] = 148
2^(a) * [1 + 2^(b - a) + 2^(c - a)] = 2^(2) * 37 → by identification, you can see:
2^(a) = 2^(2)
→ a = 2
[1 + 2^(b - a) + 2^(c - a)] = 37
2^(b - a) + 2^(c - a) = 36
[2^(b) * 2^(- a)] + [2^(c) * 2^(- a)] = 36
2^(- a) * [2^(b) + 2^(c)] = 36 → you know that: 2^(- a) ) 1/2^(a) = 1/2^(2) = 1/4
(1/4) * [2^(b) + 2^(c)] = 36
2^(b) + 2^(c) = 144
2^(b) + 2^(b + c - b) = 144
2^(b) + [2^(b) * 2^(c - b)] = 144
2^(b) * [1 + 2^(c - b)] = 2^(4) * 9 → by identification, you can see:
2^(b) = 2^(4)
→ b = 4
1 + 2^(c - b) = 9
2^(c - b) = 8
2^(c - b) = 2^(3)
c - b = 3 → recall: b = 4
→ c = 7
Mãe,J.J. linda como matemática,muito obrigado,está aperfeiçoar cada vez mais agora sinto alegria no estou aprender consigo!❤❤😂
Traduzir para inglês.
128+16+4=148
a=7,b=4,c=2
You just switched the + to - sign
Am sorry, that was a mistake. A bit after that, I noticed that I corrected that. Please ignore. The solution is still right
Should that 8 be negative or positive ?
It should be negative as the last equation but she made a mistake changing + to - and she wrongly corrected that. Does not change the final answer.
+ not -
Am sorry, it's a mistake. Please ignore, the solution is still correct. Thanks

Ok thanks. I will
Hi JJ how you come transition from 1 - 2 raised,c /2raised b = 9 to 2raised to c / 2 raised b = 8. ?????
You supposed to have
- (2 raised to c/ 2 raised to b )= 8
So what happened to your minus sign in front of 2raised to c/ 2 raised b ??????
Thanks for engaging, please highlight the time of this particular position.
