Answer:
You can simplify the fraction to get the most simplified answer then you can compare them or multiply the top or the bottom of the fraction to start comparing the fractions.

Answer:
<em>A cross section is the intersection of a </em><em><u>solid</u></em><em> and a </em><em><u>plane.</u></em>
Step-by-step explanation:
<em>A cross section</em> is the geometric place formed when an 3-D object (<em>solid</em>) is cut straight.
Imagine the shape that you can see when you cut a piece of cheese with a knife. If the piece of cheese is a cube, the resultant shape, the cross section, will be a square.
Also, you can imagine the shape formed when you cut a right cylinder (the solid) with a plane parallel to the base. In this case, the cross section will be a circle.
Depending on the form of the solid and the angle of the plane, different cross sections may be obtained.
For -(4)^7
the - is not affected by the power of 7
For (-4)to the power of7 is the same as -4 to the power of 7
It is because 7 is an odd number,the - will not change .Therefore
(-4)^7= -(4)^7
But keep in mind that if the power is an even number , the - will change to + when the situation is (-4)
For example,(-4)^4=(4)^4
