Question

Find the distance between the points (-5, 4) and (3, 1) in simplest radical form

Answer 1

use the distance formula

Answer 2

but i dont know how to do radicals

Answer 3

distance formmula is \[\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\] if you substitute your values you get \[\sqrt{(3 + 5)^2 + (1 - 4)^2}\]

Answer 4

the answer i got with distance formula was 8.54400374531753

Answer 5

yup that's right

Answer 6

but it says radical form i dont know how to do that

Answer 7

just simplify \[\sqrt{(3+5)^2 + (1-4)^2}\] then

Answer 8

3+ 5 is 8...8 squared is 64

Answer 9

1 - 4 is -3...-3 squared is 9 so we have \[\sqrt{64 + 9}\]

Answer 10

therefore radical form is \[\sqrt{73}\] got it?

Answer 11

i think so

Answer 12

thanks
