9.89-8.4+5.6=7.09 first you have to  find the square root of all numbers then you have subtract 8.4 from 9.89  then add 5.6 to that answer and you get 7.09

Aren't you supposed to find the perfect square of the numbers? I have no idea where you got all those decimals.

anonymous · Answer

I have a weird calculator so I   entered in your problem and that's what it gave me

beccab003 · Answer

You can't get a correct answer by entering this problem into a calculator. It doesn't work like that because your supposed to add and simplify. You have to find the perfect square of the number because we need to only work with whole numbers. I just have a really hard time understanding how to find the perfect square.
