1. Answer:

   15x to the power of 2

   Step-by-step explanation:

   3x × 5x = ?

   Here we will do more than give you the solution to 3x × 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, 3 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:

   3 × 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:

   3 × 5 = 15

   x × x = x2

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

   3x × 5x = 15×2

   Hope this helps,have a great day!!!!!!!!!!!!!1111111
