Answer:
27 times bigger
Step-by-step explanation:
V(sphere) = 4/3πr³
Michael: 4/3π3³ = 4/3×27π or 36π
Patrick: 4/3πr³ = 4/3πx9³ or 4/3x729π or 972π
36π to 972π is 1 : 27
Answer:
see below
Step-by-step explanation:
i.
= √(3 + 4i)
= 2 + i
ii.
= √(-8 + 6i)
= √2(-4 + 3i)
iii.
= √(-40 - 42i)
= √-2(20 + 21i)
iv.
= √i
= √i
v.
= 
=
