2^2× = 8 that is (4)×= 2^3 (2)^2× = 2^3 then × = 2^3 ÷ (2)^2 × = (2x2x2) ÷ (2×2) ×=2. final answer. |

2raised to power 2x=8x
2^2x=8x
2^2x=2^3x
2^3x-2^2x
2^3x-2x
2^x
Take log of 2^x

Wow. Interesting. I don't even know how I stumbled upon this, lol. Please, for the fun of it, I would love to share this question to some of my whatsapp groups, and reward them for answering with complete steps. Me, I no sabi maths o, but just a way to while away time in the covid-19 lockdown. I really think this would be fun. Now, it is already established that the answer = 2. But which of these people got it right and got the workings correctly? I no wan make person start dey ask me question wey I no go fit answer. Also, which set of school-level can answer this, and how much in airtime should the minimum reward be? I no wan make person give me the answer in two minutes, lol. Make dem sweat small. Thanks.

Hausa: No university student unless he studied maths in the university can provide answer to that let alone a secondary school child. Another set of people that can answer it are people that have mathematicians as friends and interact in mathematics daily( that's were I belong) similar questions before The reason why they can't answer it is product log function which is also called Lambert w. Is only in the mathematics curriculum of some mathematics courses in the university. So you can put #10000 or more depending on your pocket, Tell them the answer is 2 they should form a numerical solution to it and explain each step. Bet you no one will be able to answer it. Then you will credit me they #5,000 inside you take #5,000. 50/50. My solution is correct, use that as a template. Tell them not to use graphing. ONLY NUMERICAL SOLUTION |

Mrshape: speak for yourself, I can solve it, if he promise to reward me, note: I didn't study mathematics. |
Re: Solve This Problem & Be Hired as Consultant by macjurek(m): 7:32pm On Apr 11, 2020 |
2^2x=8x ---> Solution 2^2x=2^3x 2x=3x Divide both sides by 2 or Divide both sides by 3 x= 3/2 or x =2/3 Thanks |

Geophilip:You might be in the category of the second class of people I mentioned. Are you going to solve it with what you learn in the university or secondary school procedure, If yes bring the numerical solution and I will show you your error. I repeat again the method of solving this kind of equation numerically is only find in university mathematics student's curriculum in some schools. I will like you to prove me wrong so that I will learn from you and change my perspective. Bring numerical solution not approximate Newton Raphsson or hucus pacus. |

Mrshape:the person that asked the question didn't categorically say which method we are excepted to use, by the way I planned used any of the approximate method Newton Raphson Runge Kutta or do trial methods as far as the answer is correct and prove to be correct issues no de |

Geophilip:Oh! Now I get you. I meant the exact numerical solution. |
Re: Solve This Problem & Be Hired as Consultant by Hausa(m): 6:19am On Apr 12, 2020 |
Mrshape:The OP said that chiv seemed to be the only one that got the answer correctly. I was thinking of using his solution as a guide. What method did the chiv guy use? Also, your working is on a screenshotted paper. It'd have made more sense if you worked it like others directly. Also, the original question, is it logarithm or indices? |
Re: Solve This Problem & Be Hired as Consultant by Mrshape: 6:40am On Apr 12, 2020 |
Hausa:My workings is too technical to type with this basic keypad. It will consume my time besides let me see the chiv guys solution I have not seen it yer |
Re: Solve This Problem & Be Hired as Consultant by Hausa(m): 6:44am On Apr 12, 2020 |
Mrshape:2^2x=8x 2^2(x)=8x 4^x=8x........eqn(1) 2^2x=8x 2^2x=(2^3)x Divide both sides by 2^3 x=2^(2x-3)........eqn(2) Substitute 2^2(2x-3) for x in eqn(1) 4^(2^(2x-3))=8(2^(2x-3)) 16^(2x-3)=2^3(2^(2x-3)) 2^4(2x-3)=2^3(2^(2x-3)) 2^4(2x-3)=2^3(2^2x)/2^3 2^4(2x-3)=2^2x Equate the powers of 2 on both sides 4(2x-3)=2x 8x-12=2x -12=2x-8x -12=-6x x=2 |
