Simplify this please

(21)(x^6)(y^5) / (14)(x^2)(y^9)

Step 1: Coefficients

---This is just like simplifying fractions!

21 / 14 = 3 / 2

Step 2: Variables with exponents

---Remember to subtract exponents because this is division!

x^6 / x^2 = x^4 / 1

y^5 / y^9 = 1 / y^4

(3)(x^4) / (2)(y^4)

Hope this helps!! :)

i think the answer is b
