Roots

Roots `=sqrt(\ )`

This symbol `sqrt(\ )=` Root

You need to understand the root symbol and what is means for this bit

This tiny plant needs lots of roots to grow.

What do we have to multiply by itself `2` times to get `9`

And in this case its `3` i.e. `3xx3=9`

Answer:

`9\^(1/2)=\root2\9=3`
