Rite .. I was gonna do it like sperate n then add them together after but im so stupid at figuring out square roots without calculator, esp when they don't like, go to an even number

i cant explain it in english but u cant do that 
u can do that only w multiplication or division
Wait how u do it then
well u should know that square root 9 is 3 cause 3*3 is 9 
then u can just think that square root 7 must be x*x=7 so it's something between 2 and 3 cause 2*2 is 4 so sqaure root 4 is 2
then square root 2 is something over 1 so 1+something between 2 and 3 is over 3 so the square root 2 + square root 7 is over 3 so its >9

I CANT EXPLAIN IN ENGLISH

saying that they are the same is false because 4.059 something is not 3

it'll be like this square root 7 + square root 2 > square root 9 (idk how to add these things on the pc lol)

7 is kind of in the middle of 4 and 9 (not really but close) ( 4 5 6 7 8 9 )
so it should be around 2.5, but because it's closer to 9 then 4 it's bigger than 2.5,  (it's 2.645)
2 will be below 2 but above 1 (it's 1.414) 
so 2.645 + 1.414 = 4.059

4.059 > 3
idk how to explain it better aaaa I've finished finals and everything just got erased
well not everything but complex shit

in other words you can't just move the square root and then do 7+2 because there's no way to divine these.
and you don't do it like that

Think like this.

sqrt(4) is lower than sqrt(7).
sqrt(1) is lower than sqrt(2).

sqrt(4) is 2.
sqrt(1) is 1.
The sum of these squares is 3. And the sum of these squares is lower than the sum of sqrt(7) and sqrt(2).
At the same time sqrt(9) = 3. So that means that sqrt(7) + sqrt(2) must be higher than sqrt(9) because it is higher than sqrt(4) + sqrt(1).

Is not equal, sq(9) is < than the result of sq(7) +sq(2)
