    Indices Evaluation Question

    Sorry to trouble fellow forumers again with this indices question:

    Without using a calculator, evaluate 6^x, given that 3^(x+1) multiply by 2^(2x+1) = 2^(x+2).

    Thanks in advance!

    3^x*3*2^{2x}*2 = 2^x*2^2

    3^x*3*2^x*2 = 2^2

    6^x*6 = 4
    Now find the answer.

    Hi Sa-ri-ga-ma, you can use the command \times ( \times) to output the nice multiplication symbol
