Answer:

(x + y)^5.

Step-by-step explanation:

The (r+1)th term of (x + y)^n = nCr x^n-r y^r

Compare this with 10x^3 y^2 we get

nCr = 10 , n-r = 3 and r = 2 giving n = 3+2 = 5

5C2 = 10.

So the answer is (x + y)^5.

Answer:

It is not rational

Step-by-step explanation:

Given

$\sqrt 3 * 2.8$

Required

Rational or Irrational

$\sqrt 3 * 2.8$
