Here we will do more than give you the solution to 4x × 30x. 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, 4 and 30 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:
4 × x × 30 × x =
So now you can multiply what are the same. You can multiply the coefficients together and the x variables together as follows:
4 × 30 = 120
x × x = x2
Then you put the answers together and make the multiplication sign invisible again to get the following answer:
4x × 30x = 120x2
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:
4x × 30x2 = 120x3
4x × 30x3 = 120x4
4x × 30x4 = 120x5
4x2 × 30x = 120x3
4x2 × 30x2 = 120x4
4x2 × 30x3 = 120x5
