The real number part of the complex numbers -5+3i

Real part = -5

Step-by-step explanation:

The real part of a complex number of the form a+bi, is that which doesn't have the "i" (imaginary unit) factor. therefore the real part is "a"

In this case (-5+3i) the real part is -5.

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
