Simplify completely 14x^5y^4 +21x^3y^2/ 7x^3y
a. 2x^8y^5 + 3x^6y^3
b. 2x^2y^4 + 3xy
c. 2x^2y^3 +3y
d. 2x^2y^3 +3y^2

C.

Step-by-step explanation:

We have the expression:

which can be separeded in two terms, like this:

and now we can simplify each term, dividing the coefficients and using the exponent law (when we divide a variable we substract the exponts) and we get the following:

simplifying the exponents:

which is option C.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
