Answer:
a² = 36
Step-by-step explanation:
We are given the equation
Here, we have to simplify the equation as given in options.
Now,
Multiplying both sides with 4a, we get
Cancelling 4 in the left hand side and cancelling a in the right hand side we get,
⇒ a × a = 9 × 4
⇒ a² = 36
Therefore, the first option is correct. (Answer)
