What is 8x times 31x?

8x × 31x = ?

Here we will do more than give you the solution to 8x × 31x. 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, 8 and 31 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:

8 × x × 31 × x =

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

8 × 31 = 248

x × x = x²

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

8x × 31x = 248x²

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:

8x × 31x² = 248x³

8x × 31x³ = 248x⁴

8x × 31x⁴ = 248x⁵

8x² × 31x = 248x³

8x² × 31x² = 248x⁴

8x² × 31x³ = 248x⁵
