What is 72x times 75x?

72x × 75x = ?

Here we will do more than give you the solution to 72x × 75x. 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, 72 and 75 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:

72 × x × 75 × x =

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

72 × 75 = 5400

x × x = x²

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

72x × 75x = 5400x²

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:

72x × 75x² = 5400x³

72x × 75x³ = 5400x⁴

72x × 75x⁴ = 5400x⁵

72x² × 75x = 5400x³

72x² × 75x² = 5400x⁴

72x² × 75x³ = 5400x⁵
