Answer:
a) 6
b) 6i
c) 6i
d) -6
Step-by-step explanation:
We are going to write down the numbers as a product of prime numbers and then proceed to solve:
Note: Remember that i = √-1 and that i²= -1
a) √9(√4)
√3² × √2² = 3 × 2 = 6
Thus, the answer is 6
b) √9 ×√-4
√3² x i√2² = 3 x 2i = 6i
Thus, the answer is 6i
c) √-9.√4
i√3² × √2² = 3i x 2 = 6i
Thus the answer is 6i
d) √-9.√-4
i√3² × i√2²
3i x 2i = -6
Thus the answer is -6
