9x × 27x = ?

Here we will do more than give you the solution to 9x × 27x. 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, 9 and 27 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:

9 × x × 27 × x =

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

9 × 27 = 243

x × x = x2

9x × 27x = 243x2

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:

9x × 27x2 = 243x3

9x × 27x3 = 243x4

9x × 27x4 = 243x5

9x2 × 27x = 243x3

9x2 × 27x2 = 243x4

9x2 × 27x3 = 243x5
