Answer 10

first I applied the exponents to the numbers so 3^3 and 6^3 which is 9 and 216

Answer 11

So I got\[9\sqrt{2a}-216\sqrt{2a}\]

Answer 12

Then I subtracted assuming that both of the square root of 2a would cancel out and got -207 because 9 - 216 = -207

Answer 13

That's how I did it because that's how I learned how to do square roots and stuff lol

Answer 14

Does that make sense?

Answer 15

No prob! I hope it is right!
