Question

Simplify the following addition of radicals expression

Answer 1

\[\sqrt{25x}+\sqrt{25y}+\sqrt{16x}\]

Answer 2

\[\Large \sqrt{25x} = \sqrt{25}\sqrt{x}\]

\[\Large \sqrt{25x} = 5\sqrt{x}\]

Do the same with the other terms. Then combine like terms.

Answer 3

Would the other one look like this?
\[5\sqrt{y}\]

Answer 4

yes, what about the last one?

Answer 5

Not quite sure. I believe it would look like this.
\[9\sqrt{x}\]
\[5\sqrt{y}\]

Answer 6

Good, so the final answer is \[\Large 9\sqrt{x}+5\sqrt{y}\]
