You can put this solution on YOUR website! (0.3x)^3+2 is how I interpret the question.
0.027x^3+2
you cube 0.3
you cube x
you add them
=======
(0.3x+2)^3 is different. Start by squaring it.
0.09x^2+1.2x+4
Then multiply by 0.3x+2. There will be six terms:
0.27x^3+0.18x^2+0.36x^2+2.4x+1.2x+8
This is
0.27 x^3+0.54x^2+3.6x +8

Notice the different results for the different interpretations of the problem.
You can put this solution on YOUR website! 0.3 to the third power or *cubed*.
SO the power is basically that number times itself that many times. (For instance, if I had 3 to the fourth power, it will be: 3x3x3x3).
So here, we got 0.3 x 0.3 x 0.3. ). 0.3 times 0.3 equals 0.09. Now multiply 0.09 with 0.3. You get 0.027.
Now you have to add 2. 2 is a full number with no decimal so do not add it to the right of the decimal. Add it to the 0 on the left of the decimal. 2 plus 0.027 equals 2.027.
