find the distance from the orgin to each of the following points .If your answer is irrational,leave it in radical form.
a.(3,7)
b.(4,6)
c.(0,5)
d.(6,0)
e.(2,4)
f.(0,0)
my answers : what do they mean by leave it radical form
a.sqrt 58
b.Sqrt 52 = 2sqrt 13 or should i just leave it 52
c.5
d.6
e.i don't know ?? is it 2 sqrt5 or should i just leave it 20
f.0

Leave in radical form means don't simplify the sqrt (radical) to exact value.
Example, exact value of (sqrt(2))= 1.4142
All your answers are correct.
Always simplify radicals, ie,(like you did), but wasn't sure,
(sqrt(52)) = 2(sqrt(13)) don't leave as
(sqrt(52))
(sqrt(20) = 2(sqrt(5)) don't leave as
(sqrt(20)
