8x × 72x = ?


Here we will do more than give you the solution to 8x × 72x. 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 72 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 × 72 × x =

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

8 × 72 = 576

x × x = x2

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

8x × 72x = 576x2


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 × 72x2 = 576x3

8x × 72x3 = 576x4

8x × 72x4 = 576x5

8x2 × 72x = 576x3

8x2 × 72x2 = 576x4

8x2 × 72x3 = 576x5
