1- I didn't understand it
2).. (a/b)² (a/b)⁸
= (a/b)²+⁸ = (a/b)¹⁰
3) 3-⁵ = 1/3⁵ = 1/243
4) (x/y)"
d/dx (x/y) = (1/y)
d/dx (1/y) = 0
5) (2m⁴n³)⁵
= 2⁵ × (m⁴)⁵ × (n³)⁵
= 32 × m²⁰ × n¹⁵
= 32m²⁰n¹⁵
Answer:
DIVIDING COMPLEX NUMBERS
<em>Dividing complex numbers is a little more complicated than addition, subtraction, and multiplication of complex numbers because it is difficult to divide a number by an imaginary number. For dividing complex numbers, we need to find a term by which we can multiply the numerator and the denominator that will eliminate the imaginary part of the denominator so that we end up with a real number in the </em><em>DENOMINATOR</em>
The answer is 5x/2 because all you have to do is add 3x + 2x too make 5x and take 4-2 which is 2 and since it can't be simplified any more, just do 5x/2. Hope this helped! :)
Solution :
Given data :
20.1 33.5 21.7 58.4 23.2 110.8 30.9
24.0 74.8 60.0
n = 10
Range : Arranging from lowest to highest.
20.1, 21.7, 23.2, 24.0, 30.9, 33.5, 58.4, 60.0, 74.8, 110.8
Range = low highest value - lowest value
= 110.8 - 20.1
= 90.7
Mean = 
Sample standard deviation :
S = 29.8644
Variance = 
= 891.8823
