You are referring to an ELLIPSE.
In mathematics, an ellipse<span> is a curve in a plane surrounding two focal points such that the sum of the distances to the two focal points is constant for every point on the curve. As such, it is a generalization of a circle, which is a special type of an </span>ellipse<span>having both focal points at the same location.

Answer:
![\sqrt[4]{x^5}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%5E5%7D)
Step-by-step explanation:
A fraction exponent converts into a radical. The denominator is the index of the radical (farthest left number) and the numerator is the exponent of the base inside (the farthest right number). The base of the fraction exponent is the base number in green. To write this expression, simply the exponents into one exponent and one base.

Now convert to the radical.
![x^{\frac{5}{4}} = \sqrt[4]{x^5}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B5%7D%7B4%7D%7D%20%3D%20%5Csqrt%5B4%5D%7Bx%5E5%7D)
<span>Cross multiply
26*5x = 849 * 57
130 x = 48393
x = 48393 / 130
x = 372.25</span>
x=4.75
6×4.75=28.5
15×4.75-12=59.25
19×4.75+2=92.25
28.5+59.25+92.25=180
m<MNI= 92.25
I think this is right. I hope that it was helpful:)
