What is 7x times 5x?

7x × 5x = ?

Here we will do more than give you the solution to 7x × 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, 7 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:

7 × 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:

7 × 5 = 35

x × x = x²

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

7x × 5x = 35x²

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:

7x × 5x² = 35x³

7x × 5x³ = 35x⁴

7x × 5x⁴ = 35x⁵

7x² × 5x = 35x³

7x² × 5x² = 35x⁴

7x² × 5x³ = 35x⁵
