I could have gone farther too to make it 1.187 and could have kept on going but i stopped at 1.18 and i felt i proved my point by solving it in a pure multiplication/addition way

I sort of worked by inspection if x=1 then 6+4= 10 and that is a bit bigger than 9, so we need 9to x to increase just a little bit. x=2 9gets too big , so more trial brings it back to the 1.2ish value. Of course the mathmatical way allows for other means of working out for other values to power x and so forth
