How do i solve the square root of 30?

There is a way to work it out with a pencil and paper, but that's too complicated
to try and explain with only text, like we have here.

I don't usually recommend this for things that can be done easily on paper ...
but for square roots, your best bet is to use a calculator.

The square root of 30 does not come out even.  It starts out  5.477225...
and it keeps going and never ends.

The negative of  5.477225... is also a square root of 30.  Every number has
two square roots ... the positive and negative of the same number. 

There are 120 female rabbits and 30 male rabbits because 30 times 4 is 120 and 120 plus 30 is 150
