Determine the coordinates of the point shown.

a coordinate grid shown. there are increments of 0.5 for each grid line on each of the two axes. a point is located at 5 grid lines to the left and 3 grid lines up from the origin.

(1.5, −2.5)
(−2.5, 1.5)
(−5, 3)
(−2, 1)

X first so five to the left so it's negative and if each gridline is .5 and were are 5 gridlines aver then .5*5 so -2.5 then y is up so positive and 3 lines so .5*3 so 1.5 so coordinate is (-2.5,1.5)

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.
