X= (-4, 0, -2+2i, -2-2i)
2^12 = 4^6. (2+x)^6 = 4^6 x + 2 = 4. So x = 2. Solved in 3 seconds.
(25/4)^(9/4) = (25/4)^(2) x (25/4)^(1/4) = (25)(25)[√(5/2)]/16 = (25)(25)[√5)/(16√2) = (25)(25)(√10)/32
X= -4
Correct, but incomplete. Three other answers.
No need to resolve such the above-mentioned way since it can be easily solved as x=1, isn'i it? Why made simple things complicated?
X= 1

Powers are multiples ...nice method
this problem can be solved in your head in 2 minutes. Your solution reminded me of a joke about a gynecologist changing piston rings in a car through the exhaust pipe.
Why do you complicate so much! X^5 -1 =0 X^5 = 1 Square root of 5 both side Then X = 1 You may prove it

C=root3.......maybe
(X+2)⁶ = 2¹² multiply both side by 1/6 exponentially = x+2 = 2² x+2 = 4 x = 2 period!
thanks

If you take both sides to the 1/6 power, you get x+2=2^2; x=2. Thereafter, you could expand the expression on the left using Pascal’s triangle, and divide using synthetic division to get the other roots.
That's a great point! 😊
We could reject the complex answers. Simply make it (x + 2) = +/- 4. So x = 2, -6.

There's a saying KISS ( Keep It Simple & Stupid), but your way is Keep It Silly & Stupid.
Use 1^x to denote exp(2πix) = cos 2πx + i sin 2πx. Lemma: the solutions to x⁶ = 1 are x = 1^{n/6} for n = 0, 1, 2, 3, 4, 5. Proof: at most 6 solutions to a 6th degree polynomial equation can exist. Each of the proposed solutions checks out (just multiply their exponents by 6), and there are 6 of them. Therefore they are all of the solutions. QED. (x + 2)⁶ = 2¹² (= 4⁶) if and only if ((x + 2)/4)⁶ = 1 if and only if (x + 2)/4 = 1^{n/6} for n = 0, 1, 2, 3, 4, 5 (by the lemma), if and only if x = -2 + 4·1^{n/6}, for n = 0, 1, 2, 3, 4, 5. Those are your 6 solutions. In more prosaic and familiar terms: x = -2 + 4(cos πn/3 + i sin πn/3), for n = 0, 1, 2, 3, 4, 5. By the way: x⁶ - 1 = (x - 1^0) (x - 1^⅙) (x - 1^⅓) (x - 1^½) (x - 1^⅔) (x - 1^⅚) = C₁(x) C₂(x) C₃(x) C₆(x), where: C₁(x) = (x - 1^0) = x - 1, C₂(x) = (x - 1^½) = x + 1, C₃(x) = (x - 1^⅓) (x - 1^⅔) = x² + x + 1, C₆(x) = (x - 1^⅙) (x - 1^⅚) = x² - x + 1.
Hey, how did you get 2.5? You’ve lost me there.😮
Final answer is x= 1+ log3/2log i
(x+2)⁶=2¹² (X+2)⁶=4⁶ taking 6th on both sides 6√(x+2)⁶=6√4⁶ a√c^b=c^b÷a (X+2)^(6÷6)=4^(6÷6) X+2=4 X=4-2 X=2

what a strange stupid non realistic equation. If you draw a graph of each equation on paper, the X and Y never meet as the solution of a real quadratic equation 😮
Thats the problem of cartesian graph system, you can't depict complex numbers on it. I do study math, but we're not quite there why are complex numbers useful so i can't explain it better.
[(x+2)³]² - [(2⁶)]² = 0 ((x+2)³ - 2⁶)((x+2)³ + 2⁶)) = 0 ...so it's a matter of solving these 2 qubic equations: 1) (x+2)³ - (2²)³ = 0 2) (x+2)³ + (2²)³ = 0 1) (x+2)³ - 4³ = 0 [(x+2)-4]([x+2]² + 4² + 4[x+2]) = 0 [x-2](x²+4+4x+ 4² + 4[x+2]) = 0 [x-2](x²+4+4x+ 4² + 4x+8) = 0 (x-2)(x² + 8x + 28) = 0 ...this is TEDIOUS but hey I surely can solve it - if you pay me 😂
thanks
@rashel1 No, thank YOU! At first I thought this was just tedious and boring but it is quite interesting indeed

This question is answer oriented, if the answers are different then we can not solve this with this solution probably 🤔
X=5/4
x^x=2^2x Методом подбора: Если x=0, тогда 0^0=2^2*0 Потому что оба выражения верны одному и тому же значению: 1 2*0=0, а ноль это показатель степени, а любое выражение в нулевой степени равно одному и тому же значению - единице.
Quicker to do the multiplications from scratch although more likely to make an error that way
This guy is an idiot,
too long to solve, mine is much shorter. x power of 5 = 1 then square root of 5 both sides x = square root of 5 of 1 then x = 1
x=log200=log100+log2=2+log2 x≈2+0.30103≈2.30103 3×10^2.30103≈600.000006
As an America High School Math teacher this problem is a simple case of following math rules. It is clearly 27 like he states. There is no ambiguity.
