Option B is correct. (4 + 2i)(3 – 5i) = (3 – 5i)(4 + 2i) satisfies the commutative property of multiplication
Given two values A and B, according to the commutative property of multiplication;
This shows that the product of A and B stays the same no matter the arrangement.
From the given option, we can see that (4 + 2i)(3 – 5i) = (3 – 5i)(4 + 2i) satisfies the commutative property of multiplication where we can say;
A = 4 + 2i and B = 3 - 5i

The angle of elevation of the ground is the angle between the ground and the line of sight
The angle of elevation of the ground is 30.46 degrees
<h3>How to calculate the angle of elevation</h3>
The angle of elevation is calculated using the following tangent ratio

Evaluate the quotient

Take the arc tan of both sides

Using a calculator, we have:
= 30.46
Hence, the angle of elevation of the ground to the nearest tenth of a degree is 30.46 degrees

The sum of n odd numbers n², where n is a natural number and represents the number of terms.
<h3>What is a natural number?</h3>
The numbers that we use when we are counting or ordering, which occurs commonly and obviously in nature.
Here, given all the odd numbers from 1,3,5,7..........999.
The sum of n odd numbers, n².
999² = 998001
Thus, the sum of all the odd numbers from 1 to 999 is 998001.
