5x × 5x = ?


Here we will do more than give you the solution to 5x × 5x. 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, 5 and 5 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:

5 × x × 5 × x =

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

5 × 5 = 25

x × x = x2


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

5x × 5x = 25x2

from Research Maniacs:


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:

5x × 5x2 = 25x3

5x × 5x3 = 25x4

5x × 5x4 = 25x5

5x2 × 5x = 25x3

5x2 × 5x2 = 25x4

5x2 × 5x3 = 25x5
