Simplify the following number by using the imaginary number i.
a) -98i
b) 98i
c) -98
d) 12.8.2i

Answer 1

To simplify a number using the imaginary number i, we multiply the imaginary coefficient by i.

Step-by-step explanation:

To simplify the given number by using the imaginary number i, we multiply the imaginary coefficient by i.

a) -98i = -98 * i = -98i

b) 98i = 98 * i = 98i

c) -98 = -98 + 0i

d) 12.8.2i = 12.8 * i = 12.8i
