Write Equation: Let's first write down the equation we need to solve: xx=2.
Deal with Variable: To solve for x, we need to find a way to deal with the variable in both the base and the exponent. This is not straightforward, and there is no elementary function to represent the inverse of xx. However, we can try to find a numerical solution or use a special function like the Lambert W function for a more complex analytical approach. For this solution, we will look for a numerical solution.
Guessing x Value: We can start by guessing a value for x that seems reasonable. Since 21=2 and we are looking for 2, we can guess that x is between 1 and 2. Let's try x=1.5 and see if xx is greater or less than 2.
Calculate 1.51.5: Calculating 1.51.5 to see if it is close to 2. 1.51.5≈1.8371173070873836, which is greater than 2≈1.4142135623730951. This means our guess is too high.
Try x=1.25: Let's try a smaller value. Since 11=1, which is less than 2, we can try a value between 1 and 1.5. Let's try x=1.25 and calculate 1.251.25.
Continue Guessing: Calculating 1.251.25 to see if it is close to 2. 1.251.25≈1.3803842646028852, which is still less than 2. This means we are getting closer, but our guess is still too low.
Find Numerical Solution: We can continue this process of guessing and checking, narrowing down the interval where x lies. Alternatively, we can use a numerical method such as the bisection method, Newton's method, or a calculator with a solve function to find the value of x more precisely.

We find that x≈1.3195079107728942.
