You look to the right when you round
A centimeter ruler is more precise because it is a smaller measurement
Yes, there is a difference between 51 and 51.0 because you now know that there is a 0 behind 51 and it was not rounded to become 51.
Units can be helpful because they can help you picture the world problem or convert any numbers like feet to inches properly.

Answer:
z = 8.544[cos(20.6) + isin(20.6)}
Step-by-step explanation:
Given
8 + 3i
Required
Rewrite in trigonometric form.
The trigonometric form of a complex equation is
z = r[cosθ + isinθ]
Let a = 3 and b = 8
Where
r is calculated by
r² = b² + a²
And
θ is calculated by
θ = arctan(a/b)
Substituting 3 for a and 8 for b
r² = a² + b² becomes
r² = 3² + 8²
r² = 9 + 64
r² = 73
√r² = √73
r = √73
r = 8.544
Calculating θ
θ = arctan(a/b) becomes
θ = arctan(3/8)
θ = arctan(0.375)
θ = 20.556°
θ = 20.6 --- Approximated
Hence, z = r[cosθ + isinθ] becomes
z = 8.544[cos(20.6) + isin(20.6)}
