    Good job. The biggest takeaway for the kids is to be systematic and keep using the techniques and rules they have learned. Practice. Practice. Practice. Thanks.

  • @MaksimovAY

    Another solution is to divide both sides by 11^x. If ((7/11)^x -1)=t then the the equation is "t=sqrt(t)" => t is equal either 0 or 1. => x(1)=0; x(2)=lg2/lg(7/11)=lg2/(lg7-lg11)

  • @bandarusatyanandachary1181
    @bandarusatyanandachary1181 14 днів тому

    We can reduce the steps like this: a^x = m, then logm to base a = x instead of take logs on both sides.

  • @kylekatarn1986
    @kylekatarn1986 Рік тому +3

    the two solutions are both acceptable, even from the condtions of existance, after all it is necessary that the argument inside the root must be positive or null, and this is possible only if x

    There's a mistake after squaring both sides. By law of indices 11 to power x multiplying by itself give you 11 raised to power x square.
