Question

Please help. I don’t know the answer.

Answer 1

Answer:

y^12/5 aka the first option

Step-by-step explanation:

(9x^5y^16)/(45x^5y^4)

rules of exponents say youll do 5-5 because when dividing with exponents you subtract them

you get x^0 which is equal to 1 due to another rule of exponents

youll do 16-4 next and get 12 so y^12

now 9/45=5

the answer is (y^12)/5 (the first option)

Answer 2

(y^12)/5

9/45=1/5
x^5/x^5=1
y^16/y^4=y^12
