3x squared - (3x) squared = 0
That is 1/9x2
This is impossible as the variables are different
x2 * -3x = -3x3
5x2 + 3x + 8x2 = 13x2 + 3x = x(13x + 3)
8x to the second power times 3x to the second power (8x)2 + (3x)2 = 64x2 + 9x2 = 73x2 is one possibility, except the problem called for multiplication which would make the answer 64x squared times 9x squared = 576x to the fourth power It could also be read this way: 8x squared times 3x squared equals 24x to the fourth power. I wish my computer would do those cool little twos.
3x2 can be called "three times x squared", "three x squared", or "three times x to the power of two".
3x squared - (3x) squared = 0
Assuming your quesiton is Multiply x times 3x times 4, the answer would be 3x squared times 4.
3x squared - x squared = 2x squared
2x2 x 3x2 = 6 x4 (2x)2 x (3x)2 = 36 x4
(3x)(x2) = 3x3.Think of this as (3x1)(1x2). First multiply the numbers: (3)(1) = 3. next multiply the variables: (x1)(x2) = x1+2 = x3 (when you multiply powers with the same base, add the exponents)
That is 1/9x2

3x^2 + 6
0.3 to the 3rd power is calculated by multiplying 0.3 by itself three times. This results in 0.3 x 0.3 x 0.3, which equals 0.027. This can also be expressed as 27/1000 or 2.7%.
