Given the vectors w = <-5, 3> and z = <1, 4>, find the results of the vector subtractions. -w − z = (6,1) (4,-7) (-6,-1) (-4,7)
z − w = (6,1) (4,-7) (-6,-1) (-4,7)
w − z = (6,1) (4,-7) (-6,-1) (-4,7)

This is too long-standing now get out

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
