By the way, what you've posted isn't an equation ....What's the expression meant to be equal to ...?
the book asks to simplify without a calculator, and thanks a lot for that swift reply

call me silly but no i see how log(2)8 = 3 cause 2^3 = 8 but there's the x's and i have no clue how to simplify or solve this question :/
