Question

√(2-(-1))^2+(-1-2)^2
I know the answer is 4.24, but I don't know how to get there

Answer 1

\[\sqrt{(2-(-1))^{2}+(-1-2)^{2}}\]
okay so
2--1=2+1=3

-1-2=3

so you get

\[\sqrt{(3)^{2}+(-3)^{2}}\]

Answer 2

you can finish this I am sure

Answer 3

-1-2=-3
sorry typo of the sign

Answer 4

But they cancel each other out right?

Answer 5

9+(-9)= 0
so I just end up with √0

Answer 6

\[\huge\rm (-3)^2 = ??\]
