The correct option is (b) Even.
Correct option is (b) even
If a polynomial is a perfect square then factors repeat even number
then
p(x) = x2 + 10x + 25
= (x + 5)(x + 5)
= (x+ 5)2
If a polynomial is a perfect square then its factors repeated even number of times.
\(\therefore\) p(x) = (g(x))2 = g(x). g(x)
g(x) or its factors repeated2(even) number of times.
Correct Answer - (i) 0.28 (ii) 0.4 (iii) 0.32
Correct option is (B) irrational If n is a natural number other than a perfect square then \(\sqrt{n}\) is an irrational number.
Given that \(\vec a, \vec b\) and \(\vec c\)are unit vectors. i.e., |\(\vec a\)| = |\(\vec b\)| = |\(\vec c\)| = 1 And \(\vec a\) + \(\vec b\) + \(\vec c\) = \(\vec 0\) Then \((\vec a+\vec b+\vec c).(\vec a+\vec b+\vec c)=\vec 0.\vec...
Correct option is (A) 1/6 Possible outcomes are S = {1, 2, 3, 4, 5, 6} \(\therefore\) n(S) = 6 Number which is a perfect square and a perfect cube is 1. \((\because1^3=1\;\&\;1^2=1)\) Hence, favourable outcome...
Correct option is D) 80
