    X^2=625

    X=65

    Holy shit it works

      X=25 actually. We were wrong about the pattern; obviously the square cancels with the first digit

    This reminds me of a maths test I had when we had just been taught to calculate how many m2 an area was.

    I seem to recall seeing an example of the formula where the answer was 2 m2, ok, looking at the test there was a question that had answer to be 6 m2, but me trying to be clever, though that the 2 in m2 represented the value of the answer, wrote 6 m6.

    I failed that test…

    you’re wrong. x = -5 is also a solution lmao

      Is it though? Doesn’t it have to be (x)² then? Because -5² = -25 ?

        If you multiply a negative number with a negative number you get a positive number.

        Edit: Sorry, misread your comment, I clearly didn’t get enough sleep. In printed mathematics, the unary minus sign has a lower precedence than the exponent, but in programming, it’s the other way around, with the unary minus being applied first. So your right in printed mathematics, but wrong in programming.

          Well that is not debatable, I am talking about the difference between -5² = -25 and (-5)² = 25

            Open desmos. Graph y = x^2. Then graph y = (x)^2. Recognize that both graphs are identical. Realize the flaw in your argument.

          No they’re wrong in mathematics too. -5^2 is -25, but -5^2 is not the same as x^2 where x= -5. No brackets needed on x.

        No, because what you are doing isn’t x^2 with x=-5. It is -x^2 with x=5.

      x = 5 in this case as well, unless you can post a mathematical proof it is not.

      x^2=20922789888000

      x^2=20922789888000

    the left 2 is smaller than the right 2, so the answer is actually

    x = (size) 5
    

    But the size is represented by a whitespace symbol. Still, that’s gonna propagate and totally flummox a future calculation on that x

      She is about to silence someone, that’s for sure.

      And not using proper safety technique. Notice what’s in front of the business-end of the silencer. Yup.

    2 + 2 = 4

    2 x 2 = 4

    3 + 3 = 6

    Therefore 3 x 3 = 6
