In how many distinct ways can the letters of the word mathematics be arranged? (first, does the order matter?)
TEA [102]
Our current list has 11!/2!11!/2! arrangements which we must divide into equivalence classes just as before, only this time the classes contain arrangements where only the two As are arranged, following this logic requires us to divide by arrangement of the 2 As giving (11!/2!)/2!=11!/(2!2)(11!/2!)/2!=11!/(2!2).

Repeating the process one last time for equivalence classes for arrangements of only T's leads us to divide the list once again by 2

(X^2+y^2)^2 polynomial identify. Simplify
Alexxx [7]

Answer:

(x^{2}+ y^{2})^{2} =x^{4}+2x^{2}y^{2}+y^{4}

Step-by-step explanation:

(X^2+y^2)^2 polynomial identify. Simplify

i.e

(x^{2}+ y^{2})^{2} = ?

Solution:

We have the identity,

(A+B)^{2}=A^{2}+2AB+B^{2}

In the Question

A=x^{2}

B=y^{2}

Substituting in the identity we get

(x^{2}+ y^{2})^{2} =(x^{2})^{2}+2(x^{2})(y^{2})+(y^{2})^{2}

Also we have

(x^{a})^{b} =x^{a\times b}

(x^{2}+ y^{2})^{2} =x^{4}+2x^{2}y^{2}+y^{4}  Which is the required
