What’s the answer and how did you do it

3x6 = 729x when ever a number has an exponnet yo have to multiply the main number to itself as many times as it says.

So in this case you had to multiply 3 by itself(3) 6 times would be

(3x) x (3x) x (3x) x (3x) x (3x) x (3x) = 729x. And of course bring the variable.

x2 So when theres a varible that is by itself for example (x) you always add a 1 in front of it. so in this case x2 would be 1x2. 1 times itself(1) 2 times would be. (1x) x (1x) = 1x

729 smaller cubes would fit inside the larger cube.

Show your work so your teacher can see your thinking. I know it looks a little bit confusing but trust me the more you do it the easier it gets.

x+y=90

x=30-y=x
