Answer:
The answer is 32.
Step-by-step explanation:
Complex numbers are the number that can be written in the form of a + b<em>i</em>, where a is the real part, b is the imaginary part and<em> </em><em>i </em>is the unit imaginary part which is equal to √-1.
<h3>Solving the given equation:</h3>
2x^x + p = 0
2x^2/2 + p/2 = 0/2
x^2 + p/2 = 0
x^2 +p/2 -p/2 = -p/2
x^2 = -p/2
taking √ on both sides
√x^2 =√(-p/2)
x = √(-1)(p/2)
as we know that √(-1) =<em> i</em>
therefore
x = √(p/2)<em>i</em>
Hence, form the given choices only 32 will gives the complex number as a solution.
Now putting p = 32, we'll get
x = √(32/2)<em>i</em>
x = 4<em>i</em> is the required solution.

Odd numbers end with 1 or 3 or 5 or 7 or 9
alrighty, the last number can be 1 or 3 or 7 or 9 (we aren't given 5 in the set)
4 choices for the last number
for the other 2 numbers, we can use any other numbers
6 numbers in the set
6 choices for the first digit
5 for the 2nd
4 for the 3rd digit
so there are 6*5*4 or 120 different odd numbers that can be constructed withthe given numbers in the set
If you only have a piece of wood 7/8 feet long and you cut off a 1/4 feet piece, you are left with 5/8 foot board. all you have to do is to subtract 7/8 - 1/4.
7/8 - 1/4 = 7/8 - 2/8 = 5/8
