Option (3)
Step-by-step explanation:
If a complex number is in the form of (a + ib), real part of the complex number is 'a' and imaginary part is 'b'.
Given complex number is (-3 + 2i
)
Comparing this number with (a + ib), real part of the number will be (-3) and imaginary part of the number will be 2.
Option (3) will be the answer.
Write 658.129 in expanded form.
600 + 50 + 8 + .1 + .02 + .009
600 + 50 + 8 + .1 + .02 + .<span>009 = 658.129
</span>
658.129 in expanded form is
600 + 50 + 8 + .1 + .02 + .<span>009.</span>
