Example Question #21 : How To Multiply Variables
Simplify the following:
Possible Answers:
Correct answer:
Explanation:
Simplify the following:
To multiple this out, we need to recall how to multiple variables with exponents, and how to multiply coefficients.
To multiple the coefficients (numbers in front) simply treat them like regular multiplications.
So far so good.
To combine our x's, we will add the exponents. Recall that multiplying variables means you add the exponents.
Now, put those two together to get:
