The easier solution is to do substitution x --> 2^m. Then, we get 2^m = 32m, or m = 2^(m-5), hence m is also a power of two (if we are concerned only with the integer solutions). The smallest value m=8 satisfies the equation. hence m=8, x=2^8 = 256.

Your answer is right but when you analize the graphic of 2^x and x^32 the graphic of both functions intersects at three points: x ≈ -0.979, x ≈ 1.022 AND x = 256. For those first two solutions I couldn't find an analytical way to calculate their exact value. I know they are irrational but I couldn't find a way to express them with roots or even something with the number e.

Méthode intuitive. On remarque que 2^8=256 et que 8*32=256 Du coup on suppose x=2^8 puis on vérifie : 2^256=(2^8)*32=2^(8*32)=2^256

But there should also be a negative real solution, since (−x)³² = x³² and 2ˣ = (1/2)⁻ˣ, so we get an equation (1/2)⁻ˣ = (−x)³² for −x ∈ ℝ.

It is bad enough that only one solution is found. What is worse, is that uniqueness is not even discussed. Why so many people like to lecture on mathematics without first learning the basics of ``mathematical culture".

there is a faster and more accurate way: x > 0, obvious x cannot be non integer rational number because then LHS = irrational and RHS = rational. So, x > 1 and x is a natural number. Let x be 2 to the power of k. k > 0. So, 2 to the k = 32k. So, 2 to the (k-5) = k. Obvious solution: k = 8, so x = 256. Draw graphs for y = k and y = 2 to the (k-5). For k>8 they cannot meet again (show with differentiation). For 1

AI Resolving: To solve the equation \( 2^x = X^{32} \) for \( X \) given a specific value of \( x \), follow these steps: 1. Take the natural logarithm (ln) of both sides of the equation: \[ \ln(2^x) = \ln(X^{32}) \] 2. Use the logarithmic identity \( \ln(a^b) = b \ln(a) \): \[ x \ln(2) = 32 \ln(X) \] 3. Solve for \( \ln(X) \) by dividing both sides of the equation by \( 32 \ln(2) \): \[ \ln(X) = \frac{x \ln(2)}{32} \] 4. Exponentiate both sides with the base \( e \) (Euler's number) to solve for \( X \): \[ X = e^{\frac{x \ln(2)}{32}} \] Now, substitute the value of \( x \) into this formula to find the corresponding value of \( X \). For example, if \( x = 4 \): \[ X = e^{\frac{4 \ln(2)}{32}} \approx e^{\frac{\ln(2)}{8}} \approx 1.0905 \] This method allows you to calculate \( X \) for a given value of \( x \). Therefore, for ( x = 4 ), the value of ( X ) is approximately ( 1.0905 ).
