1) The value of $\log_e\left(\sqrt e\right)$ is …….

A) $\frac12$
B) $\frac22$
C) $\frac32$
D) $\frac42$

View Answer

A) $\frac12$

Explanation:We are given:
$\log_e(\sqrt{e})$
Shortcut Method:
Recall:
$\log_e(e^x) = x$
Now, write $\sqrt{e}$ as an exponent:
$\sqrt{e} = e^{1/2}$
So:
$\log_e(\sqrt{e}) = \log_e(e^{1/2}) = \frac{1}{2}$
Correct Answer: $\frac{1}{2}$

2) Cardinal number of the set A={-2,-1,0,1,2} is

A) 5
B) 4
C) -2
D) 2

View Answer

A) 5

Explanation:To find the **cardinal numberof a set, simply **count the number of distinct elementsin it.
Set A = {−2, −1, 0, 1, 2}
Number of elements = 5
Correct Answer: A. 5

3) The zeroes of the quadratic polynomial x²+24x+119 are

A) one positive and one negative
B) both positive
C) both negative
D) none of the above

View Answer

C) both negative

Explanation:We’re given the quadratic polynomial:
$x^2 + 24x + 119$
To find the nature of its zeroes, we can factor it.
Try splitting the middle term:
We need two numbers that add up to 24and multiply to 119.
Check factors of 119:
119 = 17 × 7
And:
17 + 7 = 24
So we can write:
$x^2 + 24x + 119 = (x + 17)(x + 7)$
The zeroes are:
$x = -17,\quad x = -7$
Both are negative.
Correct Answer: both negative

4) What is the degree of the polynomial $7u^6=\frac32u^4+6u^2-8$

A) 7
B) $-\frac32$
C) 6
D) -8

View Answer

C) 6

Explanation:Shortcut: The degreeof a polynomial is the highest power of the variable.
Here, the highest exponent of $u$ is:
$\boxed{6}$

5) H.C.F. of 8, 9 and 25 is.

A) 0
B) 1
C) 2
D) 3

View Answer

B) 1

Explanation:To find the HCF (Highest Common Factor)of 8, 9, and 25:
8= 2³
9= 3²
25= 5²
These numbers have no common prime factor.
Shortcut:
If no prime factor is common, then HCF = 1.
