    It’s mistake in your website math exersice no 2.4 Q1Part3 step no 5 mistake)(x-6) (y2)-3 (y)-4is not true right step is (x-6) (y2) (z-4) it is
    true step (z-4)

    1. Author

      There is no mistake found in it.

    2. Arfan

      The solution is ok . Here the question is to understand the addition and subtraction of power. So the rule ” X^0 = 1 ” will not be implement here.
