What is 3x times 40x?

3x × 40x = ?

Here we will do more than give you the solution to 3x × 40x. 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 40 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 × 40 × x =

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

3 × 40 = 120

x × x = x²

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

3x × 40x = 120x²

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 × 40x² = 120x³

3x × 40x³ = 120x⁴

3x × 40x⁴ = 120x⁵

3x² × 40x = 120x³

3x² × 40x² = 120x⁴

3x² × 40x³ = 120x⁵
