Question

Simplify the following expression: (21x^7y^2)/(7xy).
A. 3x^3y
B. 3x^6y
C. 3x^9y^2
D. 3x^11y

Answer 1

B. 3x^6y

Answer 2

But you should know how to do it. Like when you are dividing x^7/x, the answer would be x^6, because when you divide those, you are actually subtracting the exponents.

Answer 3

(21x^7y^2)/(7xy)
(21x^7)y^2/(7x)y
(3x^6)y
