first how do i get the square root symbol

second

i am down to
the square root of 90a
over
45 (no square root)

how do i reduce that

i can see factoring out 9 from each number but that would leave

the square root of 10a

over
5

and the book wants the square root of 10a
over
15

sqrt(?)

> second i am down to the square root of 90a over 45 (no square root)
sqrt(90a) / 45

> i can see factoring out 9 from each number
NO; all you can do is sqrt(9 * 10a) / 45

I'll let you finish it...
