Answer:
Option B is correct that is cube root of 9.
Step-by-step explanation:
We have been given the expression:
after solving square power
It can be rewritten as 
Which is the cube root of 9
Hence, Option B is correct That is cube root of 9
Option A is discarded because square gets solve then only we get 9
Option C and D are discarded because square will be solve we will get 9.

Step-by-step explanation:
n(D) = 4
Step-by-step explanation:
Given Data:
Set D = {4, 6, 8, 10}
The number of elements in a set is called the cardinal elements (or) cardinality of the sets. This is denoted by n(A).
Here it is denoted by n(D).
The number of elements in the set D is 4.
The cardinality of the set is 4.
Hence, n(D) = 4.
Circle equation:
(x-a)^2 + (y-b)^2 = r^2
x^2 - 2ax + a^2 + y^2 - 2by + b^2 = r^2
x^2 + y^2 + a^2 + b^2 - 2ax - 2by - r^2 = 0
_______________________
4x^2 + 4y^2 + 36y + 5 = 0
4x^2 + 4y^2 + 36y + 5 +0x + 0y = 0
(-2ax = 0x)
-2a = 0
a = 0
(-2by = 0y)
-2b = 0
b = 0
____________________
And now:
a^2 + b^2 - r^2 = 5
0^2 + 0^2 - r^2 = 5
0+0-r^2 = 5
r^2 = -5
Since there is no negative radius, we say that it is not an equation of a circle
Answer:
Step-by-step explanation:
A hole is an input value that makes both numerator and denominator equal to zero.
<u>Let's factorize the numerator and denominator:</u>
- 3x² - 108 = 3(x² - 36) = 3(x + 6)(x - 6)
- x² + 2x - 24 = x² + 6x - 4x - 24 = x(x + 6) - 4(x + 6) = (x - 4)(x + 6)
<u>We have same factor of x + 6:</u>
- x + 6 = 0
- x = - 6 is a hole
