Alright, so on a worksheet today, she worked out a simple math problem. Or so she thought. Upon closer inspection, her answer is completely wrong, in addition to the question not having any sort of non-decimal answer.
The Question:
Given: 6 times (X^2)=36
X^3=?
Her answer:
X^3=3 times cubed root of 8
Her answer is obviously wrong. first off, cubed root of 8 is 2. no matter, it comes out to 6 either way.
second, if you take the cubed root of 6 (in order to get X to the 1st power), it comes out to 1.81712059. This squared, to come out with X squared (as in the first part of the problem), multiplied by 6, does NOT come out to 36.
in fact, nothing squared times 6 equals 36 (except, obviously, the square root of 6, rather than the CUBED root)
Perhaps I'm missing something, but if anyone works this out and finds that it does in fact come out as X cubed equals 6, but at the same time X squared times 6 equals 36, please tell me how, because apparently I'm lost.
I know I'm right, I just want to see if I missed something.
