Here we will do more than give you the solution to 3x × 2x. We will also explain and teach you how we came up with the answer, so you can understand it and solve similar problems in the future without help.
In this problem, 3 and 2 are the coefficients and two Xs are the variables. When a coefficient is next to a variable there is an invisible multiplication sign. So you could rewrite the problem as follows:
3 × x × 2 × x =
So now you can multiply what are the same. You can multiply the coefficients together and the x variables together as follows:
3 × 2 = 6
x × x = x2
Then you put the answers together and make the multiplication sign invisible again to get the following answer:
3x × 2x = 6x2
If you multiply two same variables with exponents, you simply keep the variable and add the exponents. Also x with no exponent is the same as x1.
Here are some problems with answers that you should know based on what you learned on this page:
3x × 2x2 = 6x3
3x × 2x3 = 6x4
3x × 2x4 = 6x5
3x2 × 2x = 6x3
3x2 × 2x2 = 6x4
3x2 × 2x3 = 6x5
