Number two is A........hope this helps
Hi there!

First we split up the square root into two parts.

Now we calculate the value of the square roots which have an integer as a solution

Multiplying the integers gives us our next step.

And finally we add up the roots.
Here is the answer:
Expanded Form: 50 + 7 + 0.03 + 0.006
Word Form: Fifty plus seven plus zero point zero three plus zero point zero zero six
