6^3x+2=216 rational exponents how do you solve and what are the steps to finding the answer thnx

6^3x+2=216
The steps on solving this problem is first write MDAS which means mutliplication is first so first you multiply 6^3x+2  after your done you get 18^x+2=216
and thats how you do it. (I hope that help cause I showed my teacher this question she kinda helped me with it..)

So you want to find the volume of the shape. you would first find the volume of the half a circle at the bottom. to find the volume of a circle you would use the equation volume= 4(3.14) times radius to the third power over three. then divide the answer you got there in half because it is half a circle. after that you would find the volume of a cone which is base times height and add your answers together. remember that they only gave you half of the base.
