4x × 34x = ?


Here we will do more than give you the solution to 4x × 34x. 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 34 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 × 34 × x =

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

4 × 34 = 136

x × x = x2

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

4x × 34x = 136x2


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 × 34x2 = 136x3

4x × 34x3 = 136x4

4x × 34x4 = 136x5

4x2 × 34x = 136x3

4x2 × 34x2 = 136x4

4x2 × 34x3 = 136x5
