Because you can just simplify to have 1-2 terms only. Eg:
13+2y+4y (this is a trinomial as it has 3 terms) can be simplified to just give 13+6y

Answer:
3x^7 / y
Step-by-step explanation:
√63x^15y^9/√7xy^11
= √ [(63/7) x^(15-1) y^(9-11)
= √9x^14y^-2
= √9x^14 / y^2
= 3x^7 / y
First you find a common denominator, which is 12 ( as 4,3 and 6 all go into 12). So 2/4 becomes 6/12, as 4 multiplied by 3 is 12 and whatever you do to the denominator you must do to the numerator. Then 2/3 becomes 8/12. And 2/6 becomes 4/12. If you put these in order the answer is:
2/6, 2/4, 2/3
Symmetry means that if you split it in half, the two sides would be equal. For example, the letter X is symmetrical.
