Here we will do more than give you the solution to 23x × 98x. 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, 23 and 98 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:
23 × x × 98 × x =
So now you can multiply what are the same. You can multiply the coefficients together and the x variables together as follows:
23 × 98 = 2254
x × x = x2
Then you put the answers together and make the multiplication sign invisible again to get the following answer:
23x × 98x = 2254x2
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:
23x × 98x2 = 2254x3
23x × 98x3 = 2254x4
23x × 98x4 = 2254x5
23x2 × 98x = 2254x3
23x2 × 98x2 = 2254x4
23x2 × 98x3 = 2254x5
