2x^3. To solve this, break the coefficients away from the variables to make it easier. 2*1 (which is implied before the x) is 2. Then x*x^2 is x^3 (not 3x, which is a very common mistake). Then you put the numbers back together to get 2x^3.
It is: -2x squared
(2x)2(x) = 4x3
2x+x is 3x
2x2 x 3x2 = 6 x4 (2x)2 x (3x)2 = 36 x4
2x times 4x is 8x squared- then that times x is 8x to the power of three.Mathmatically represented as 8x^3
2x to the fourth
It is: -2x squared
No. x squared is x times x, whereas 2x is x + x.
(2x)2(x) = 4x3
No, x + x equals 2x. x times x equals x2. (x times x equals x squared.)
2x+x is 3x
2x2 x 3x2 = 6 x4 (2x)2 x (3x)2 = 36 x4
2x times 4x is 8x squared- then that times x is 8x to the power of three.Mathmatically represented as 8x^3
8
We know that when you submit questions you aren't free to use the right format to make the mathematical terms crystal clear. It is likely that you mean "x squared times 6 plus x squared times 2", which is clearer. You can factor out the "x squared" and you will see that you get "x squared times 8". You COULD mean (6x) squared plus (2x) squared, which would be different. 6x times 6x would equal x squared times 36, so your answer will be much different.
3x squared - x squared = 2x squared
The answer depends on whether or not the 8 is part of the squared: (8x) squared times 2x = 128x38 x2 times 2x = 16x3
