<span><u><em>The correct answer is:</em></u>
180</span>°<span> rotation. 
<u><em>Explanation: </em></u>
<span>Comparing the points D, E and F to D', E' and F', we see that the x- and y-coordinates of each <u>have been negated</u>, but they are still <u>in the same position in the ordered pair. </u>
 <u>A 90</u></span></span><u>°</u><span><span><u> rotation counterclockwise</u> will take coordinates (x, y) and map them to (-y, x), negating the y-coordinate and swapping the x- and y-coordinates. 
<u> A 90</u></span></span><u>°</u><span><span><u> rotation clockwise</u> will map coordinates (x, y) to (y, -x), negating the x-coordinate and swapping the x- and y-coordinates. 
Performing either of these would leave our image with a coordinate that needs negated, as well as needing to swap the coordinates back around.  
This means we would have to perform <u>the same rotation again</u>; if we began with 90</span></span>°<span><span> clockwise, we would rotate 90 degrees clockwise again; if we began with 90</span></span>°<span><span> counter-clockwise, we would rotate 90 degrees counterclockwise again. Either way this rotates the figure a total of 180</span></span>°<span><span> and gives us the desired coordinates.</span></span>

The number that is not irrational is  . The correct option is the second option
. The correct option is the second option 
<h3>
Irrational numbers </h3>
From the question, we are to determine which of the given options is not irrational 
Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q, where p and q are integers. 
 is a repeating decimal and it can be expressed as a fraction
  is a repeating decimal and it can be expressed as a fraction

∴  is not an irrational number. It is a rational number
 is not an irrational number. It is a rational number
The other options cannot the expressed as a fraction.
Hence, the number that is not irrational is  . The correct option is the second option
. The correct option is the second option

The given expression is

We have to write it in a different way and for that, we have to check the factors of 125 and x^4 .
And factors of 125 are 25 and 5.

Radical 25 equals to 5 and radical  is
   is   .
.
So we will get

And that's the another way to write the given expression .
