Final Answer:
1. The expanded and simplified form of
Step-by-step explanation:
To expand and simplify
, we use the distributive property. We distribute
to both terms inside the parentheses.
The expression becomes
. To simplify this, we multiply the terms inside each square root:
.
Finally, we express
and simplify further to
. The simplified and expanded form is
This is the final answer after expanding and simplifying the given expression.
In summary, by distributing
to each term inside the parentheses and simplifying the square roots, we obtain
, which can be further simplified to
.
