Answer 1

Answer:

The imaginary part is √(-16) or 4i

Step-by-step explanation:

√9+√(-16)

=3 + 4√(-1)

=3+4i

The imaginary part is √(-16) or 4i

Hope this help.

Answer 2

Concept:

Complex numbers are the numbers that can be expressed in the form of a+ib where, a,b are real numbers and  ‘i’ is an imaginary number called “iota”. The value of i = (√-1). For example, 1+3i is a complex number, where 1 is a real number (Re) and 3i is an imaginary number (Im).

Combination of both the real number and imaginary number is a complex number.

Given:

complex no. √9+√(-16)

Find:

The imaginary part of complex no. √9+√(-16) is:*​

Solution:

√9+√(-16)

⇒3 + 4√(-1)

⇒3+4i

Therefore, The imaginary part is √(-16) or 4i
