What is 2x times 18x?

2x × 18x = ?

Here we will do more than give you the solution to 2x × 18x. 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, 2 and 18 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:

2 × x × 18 × x =

So now you can multiply what are the same. You can multiply the coefficients together and the x variables together as follows:

2 × 18 = 36

x × x = x²

Then you put the answers together and make the multiplication sign invisible again to get the following answer:

2x × 18x = 36x²

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:

2x × 18x² = 36x³

2x × 18x³ = 36x⁴

2x × 18x⁴ = 36x⁵

2x² × 18x = 36x³

2x² × 18x² = 36x⁴

2x² × 18x³ = 36x⁵
