Assuming that 'lg' means 'log' (either base 10 or base 2):

3 lg( x )  =  lg( x3 )

So, the equation becomes  3 lg( x )  =  lg( 10 )     --->     lg( x3 )  =  lg( 10 )     --->     x3  =  10

                                                                                                                         --->       x  =  cuberoot( 10 )
