Answer:
Last Option
[tex] {y}^{6} \div {y}^{2} [/tex]
Step-by-step explanation:
This is because,
As,
[tex] {a}^{x} \div {a}^{y} = {a}^{x - y} [/tex]
Here ,
[tex] {y}^{6} \div {y}^{2} [/tex]
[tex] = {y}^{6 - 2} [/tex]
[tex] = {y}^{4} [/tex]
And here the result does not simplify to,
[tex] {y}^{3} [/tex]
Hence, Last Option is the correct answer
