Simplifying a basic radical expression root

The video tutorial explains the process of simplifying mathematical expressions, specifically focusing on the square root of 14. It begins by discussing the need to simplify or find the value of expressions. The tutorial then explores whether the square root of 14 can be simplified by rewriting it as a product of factors, but concludes that it cannot be simplified further. Finally, it demonstrates that while sqrt 14 remains unchanged, expressions like sqrt a^2 can be simplified to 'a', leading to the final answer of 'a times sqrt 14'.

Why can't we simplify sqrt(14) further?

What is the final expression when combining sqrt(a^2) and sqrt(14)?
