The property "a^log(b) base a" is only valid for b > 0 due to the nature of logarithmic function. While a quadratic equation does not have a domain restriction and we can have a negative solution, the involvement of log function in the equation x^2 + 7^log(x) base 7 - 2 = 0 restricts any negative solution simply because how a logarithmic function is defined.
Sir muje apki classes lete hue 2 years ho gye but aaj yk ek hi kami rhi hai aap phadate bhaut acha hai sabh kuch acha krwate ho but jee ke study material bi solve krwaya kro kyo ki sabhi type k questions ki practice nhi ho paati hai .
I was Facing Problems In My Coaching DPP so I Thought I Have Doubts In Logarithm Equation So i Came Here But The Level Of Question Is Soo Low Despite Not Having Concepts Clear i was Able To Solve all The Question With ease😐

Sir aapne iss sawal me negative wale ko reject kyu nahi kiya??? (40:12)
arre woh -ve nhi hai woh 10^-√5 hai woh 1/10^√ 5 hota hai toh woh bhi =ve hiii hoga 😁😁😁
Because vo rhs mei ha naki log ke sath (lhs mei).
at 1:00:00 my answer is getting x=3,2/3 please confirm if 2/3 is an answer or not
4 solutions given as answer does not compromise.
When putting -2 again answer coming correctly in 7^log x to the base 7 as -2-2+4 =0.
