10/2 is an improper fraction. So, change it to a mixed number. 10÷2=5

5 is the mixed number and is the equivalent fraction. You can also do 5/1 which is also equivalent.

You can apply the ^2 out of parenthesis to 3 and variables in parenthesis.

(3x^2yz^4)^2 will now be 3^2 x^4 y^2 z^6

You can't simplify it by that much besides the 3^2 which is simplified to 9, so your final simplified equation is 9 x^4 y^2 z^6.

**Answer:**

yes,given length can form right angle triangle.

**Explanation:**</h3>

Class boundaries need to be defined so that a point on the boundary is unambiguously placed in one class or the other. With these boundaries, a value of 120 might be placed in the first or the second class—<em>we don't know which</em>.

_____

It is customary to define class boundaries between data values 60.5–120.5, for example, so that no data value can fall on the boundary, or as a semi-open interval [60, 120), so that a boundary value is clearly placed into a specific class.
