    The Wrong Answer At the video time 7:34, while doing this problem, she got it wrong. The problem was (4x^3+13x^2-5x+1). Her answer was 101. The problem’s actual answer was -27. The last bracket problem was: (-256+208+20+1). Instead of putting in -256, she took half of it, and wrote -128.

    I guess they are considering root2 cube as root2 x square of root2 then sq of root2 = 2 and then multiply it with 27 we will get 54 and write that root2 as it is... I don't know what logic I've applied but that's how only it can come 54 root2 I guess...
