You can't even solve this with a standard scientific calculator, other than by trial and error, without a special case given. The general solution to: x^x = A is: x = ln(A)/LambertW(ln(A)) Since there is no LambertW function on standard scientific calculators, you'd need a very advanced calculator to solve this one. Either that, or the know-how to program the details of LambertW.

I knew it would be much faster simply plugging in all the answers until it was right, but I found it much more satisfying to generalize the solution mathematically rather than simply guess. I started with a system of equations: x^x=(2^a)^b where ab=2048 and 2^a=b The end solution here would of course be "b", and "a" is some unknown introduced with the intent to be solved out. Knowing 2048 is 2^11, putting "a" in an assumed form of 2^c you can work through it to form 2^(2^c+c)=2^11 which simplifies to 2^c+c=11, and you can easily see that c=3. Plugging all the way back up you get a=8 and b=2^a=2^8=256

For any solution, could you use Lambert W function? i.e. When x^x = 69, Rewrite as: x * e^-(ln(69) / x) = 1 Let ln(69) / x = α, While ln(69) / α = x: (ln(69) / α) * e^-α = 1 Implied Lambert form: α * e^α = ln(69) Define Lambert W function: W(n) * e^W(n) = n Return α = W(ln(69)) So, x = ln(69) / W(ln(69))

An algebraic approach to this problem will be: 2^2048=2^(2^m x 2^n) [Since, a^p x a^q= a^(p+q)] Therefore, m+n=11 [Since,2^11=2048] Now, 2^(2^m x 2^n)={2^(2^m)}^(2^n) From the Q. 2^(2^m)=(2^n)=x Taking log the the base 2 both sides, (2^m)=n We can observe that 2^3=8 & 3+8=11 Therefore,m=3 & n=8 Hence, x=2^n=2^8=256 Note: You can alwys solve by the traditional methods but this is the one that first came to my mind.

I know it's not directly related, but I'm curious, if rules of exponents state (a^b)^c = a^(bc) then if I had something like (2^x)^x it makes sense it should be 2^(x^2), but this seems wrong. hmm if I took (x^x) and raised 2 to that power, what is the standard symbolic difference between 2^(x^x) and (2^x)^x? Exponents are often written without parens, what are the implied parentheses in this case?

for any x^x = z equation, x = e^W_k(log z) or equivalently x = e^W_k(ln |z| + i(θ + 2nπ), and for any x^x = 2^b equation, x = e^W_k(b/log 2) or equivalently x = e^W_k(b/(ln 2 + 2nπi)) where W_k is any branch of the Lambert W function/product log and n is any integer, and θ is the argument/angle of the possibly complex number z or b, this means there are not only infinite possible values due to infinitely many multiples of 2πi, but also due to the infinitely many branches of the product log, also it's pretty rare to find an equation of that type with an integer solution. Note that you have a real solution to the equation only for any b/log 2 greater than or equal to -1/e. the way you solved the equation though, that's not how you solve equations and if it were different by one unit the method wouldn't hold

The second step being 4^1024 could have also been solved a different way. If the exponent is an odd number, the last number of the answer should always be 4. If even, it's always 6. This is always the case when it comes to 4 raised to x.

The answer is D easily without calculation. The number on the right is a power of two, meaning the number x represents can be only factored by 2 or the power of 2, which is D.

You can use elemination. 0,40,69420 can easily be eleminsted as any power of 2 can never give unit digit 0. Now 8 can't be the answer,simply evaluate and estimate the value. Only option left is 256.

Only B and D are represented by n squares of 2. We can also choose D by process of elimination, since we can see at a glance that 8 is too small.

@@ZucchiZ The base and exponent need to be equal, so he just took from the exponent in the smallest possible increment until he arrived at a form where the base and exponent matched. Sure it works, but it's potato levels of interesting. I'm more interested in the algebraic relationship. I couldn't quite get my equations to make sense, but I think it can be expressed as a system of two equations.

Write 2^2048 in a different format, make the base bigger than the exponent. Easy way to do this is to say (2^2)^1024. 4^1024. Keep doing this and you get 256^256.

0, 40 and 69 420 are excluded because they are not powers of 2 (65 636 would be). It can't be 8 as 8^8 is 4^16 is 2^32. So it must be 256.

2,4,8,16,32.... The unit place follows a pattern of cyclicity. It repeats after 2,4,8,6,2,4,8,6,... After every 4th term. 2048÷4 = 512. So, the last unit digit has to be a 6. Based on this, It has to be 256^256.
