What is 4x times 10x?

4x × 10x = ?

Here we will do more than give you the solution to 4x × 10x. 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, 4 and 10 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:

4 × x × 10 × x =

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

4 × 10 = 40

x × x = x²

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

4x × 10x = 40x²

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:

4x × 10x² = 40x³

4x × 10x³ = 40x⁴

4x × 10x⁴ = 40x⁵

4x² × 10x = 40x³

4x² × 10x² = 40x⁴

4x² × 10x³ = 40x⁵
