Can someone help me please

Answer:
B. [tex]9 x 10^{4}[/tex]
Step-by-step explanation:
When you solve the equation, you have to be able to know and recall your perfect squares. Well first, I would use PEMDAS to solve this equation. [tex]10^{4}[/tex] is the first thing to solve. Which the answer is 10,000. Then multiply 10,000 by 9 which the answer is 90,000.
90,000 is a perfect square (square number). Which is the reason why B is the answer.
