5x4 = 7_13

20=7_13

20=7+13

20=20

sqrt(361) = 19

X^(2/3) = CubeRt(X^2)

Ab outlier is a piece of data which is not within the "normal" boundries of a data set.

For Example: 

here is how i am interpreting this equation: (((-1)^(5^2))/(-2)) -3

which would be (-1/-2) - 3

= -2.5

However it is hard to tell what your equation above is, and so it may be something totally different based on parenthesis. and what is in the numerator and denominator.

a^2 + b^2 = c^2            

(90 ft)^2 + (90 ft)^2 = c^2

16200 = c^2 

127.2792206135785544 = c 

c = 127.3 ft

4x + 2y = -8

3x - 2y = 29

7x + 0y = 21

7x = 21

x = 3

It would appear that their is an error in the problem, unless it is missing tax or whatnot.
