4x^2. To solve this it's easiest to look at the coefficients and variables separately. 2*2=4, so that's your new coefficient. Then x*x=x^2 (not 2x, which is a very common mistake). Then you put your answers together to get 4x^2.
4x
2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
The answer depends on whether or not the 8 is part of the squared: (8x) squared times 2x = 128x38 x2 times 2x = 16x3
x2 × 2x = 2x3
It is: -2x squared
(2x)2(x) = 4x3
2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
(2x)2 times (2x)2 = 16x4 (2x2) times (2x2) = 4x4
2x * 2x (2*2=4) therefore, 2x*2x equals 4x2.
